Downtown Bryan Shell

The restaurant section is the one on the left (picture by author, 9/21)
In what is possibly the newest (and last) Zip'N built (2010, replacing an older Zip'N Shell at 200 North Texas Avenue), this downtown gas station at 208 North Texas Avenue takes up three quarters of the block and is the main gas station/convenience store anchoring the downtown area (some older options take up the slack to the north and west).

At the northeast corner of the block (the original 208 N. Texas Avenue) was Shining Star Detail, which relocated. The rest of the lot (the part that Shell occupies) was a parking lot, presumably for the office building occupying the remainder of the block. Catty-corner to the Shell (at 24th Street) is a Shell Rapid Lube, likely associated with the gas station for years (it predates the new store, probably decades old).

Another look at a slightly different angle.
The tenant to the right of Zip'N appears to have always been empty, but to the left was originally a Krispy Krunchy Chicken very briefly in the mid-2010s, then the sign got modified when it became Bellon's Kung Pao Express (which operated for less than a year; it's supposed to look closer to this). Esmeralda's Taqueria has been here since late 2016.

Across the street is a Dairy Queen, which I photographed the exterior of but due to new site "rules", outlined in the Harmony Science Academy post, it can't make the cut, but perhaps you might see it on the City Directory pages of Carbon-izer soon. Zip'N qualifies because of the restaurant on site (and given that it has the same address, I assume it's connected to the store) has changed a few times.

UPDATE 04-16-2023: As of late April 2023, this gas station has converted to a Sunoco. The nearby lube station is now a Castrol.

Shell at Holleman and Harvey Mitchell

From June 2013 by author. This post was actually planned to go up in late 2014, but it got pushed back for reasons.
My little corner of the world got two big upgrades in 2004: the completion of Jones-Butler Road in November of that year (connecting the "Marion Pugh Road" segment between North Dowling and Harvey Mitchell Parkway to I&GN Road at Rock Prairie Road West) brought a new avenue to access Rock Prairie Road, and a new modern gas station built at a small field at the intersection of Holleman and Harvey Mitchell, which at the time was a sleepy little terminus of a segment that was almost never driven on...why go straight across the steep railroad crossing and make an unprotected left, when we could head down Wellborn and take a long ramp directly to FM 2818?

This "new modern gas station" was a Shell and featured a Wendy's, with one of the first Rattlers'-branded gas stations in town. Rattlers' Country Store as it was named originally, was a local operation that featured clean, well-run stores with their own distinctive branding. There was a car wash (which I don't think I ever used), a Subway (2048 Holleman West, opened 2005), and Holleman Cleaners (2046 Holleman West), a small dry cleaning operation. Neither of these connected to each other like Wendy's and Rattlers' did (Rattlers' has the address of 2050 Holleman, with Wendy's being 2052, but known to use 2050 sometimes).

There were a few minor changes that went on with the gas station. The Wendy's remodeled in the early 2010s but never saw its exterior sign change—but in the mid-2010s, the gas station signage received a revamp, adding electronic signage and a new Wendy's logo (an old "movable numbers" board closer to the ground was changed to just read "SCANTRONS"). The car wash went away sometime around 2009 and was replaced by a building, soon occupied (after several months) by one "Liquor Mart" (2054 Holleman Drive West).

The Rattlers' changed logos at some point (dropping the "Country Store" branding) and briefly adding a "Froggies Yogurt" inside (replacing a small kiosk with foil-wrapped tacos). Froggies went away shortly after the Rattlers' chain was sold to Sunoco (which owned Stripes) in 2016. This meant that the gas station and the new Stripes on the other side of Holleman were now under common ownership.

In Febraury 2018, the Shell became a Sunoco. This was likely due to a contract regarding Sunoco stations being kept when Sunoco officially sold its gas stations to 7-Eleven a month or so prior, which meant that the Rattlers' was officially owned by 7-Eleven. Two years later, Holleman Cleaners (which had closed down in fall 2019) turned into "Elevated CBD + Smoke". Rattlers' never converted to Stripes or 7-Eleven, and by 2020, Rattlers' closed down around midnight while the Stripes across the street maintained a 24-hour operation, giving it an edge in business. The Wendy's closed in the fall of 2020 (see the first update below) and the main Rattlers went out with it, taking down the entire gas station with it. Only Subway and Elevated remained. As of this writing, the station seems to have come back to life. The Shell name and canopy has been restored (though the canopy just has the symbol instead of the writing, a change that came about starting in the mid-to-late 2010s), the facade was repainted maroon and white, with the convenience store being called "Campus Corner", and the Wendy's also being repainted and altered to be a Burger Mojo. We'll see how it goes this time... 

UPDATE 10-14-20: Wendy's, which has been in the store since around January 2005 (give or take a month), permanently closed in or around September 30, 2020. The reason for this closure is still yet unknown. Also rewrote some minor parts in the article.

UPDATE 12-02-20: A check on December 1st revealed that sometime in November, Rattlers (and the entire gas station component with it) has closed. Elevated CBD + Smoke and Subway continue to operate, while Burger Mojo is planned to go into the former Wendy's.
UPDATE 01-21-21: The station has since reverted to Shell with a new convenience store and restaurant. The main description has been rewritten with the title altered to remove "Sunoco".
UPDATE 02-04-21: Campus Corner has opened in the last few days. The décor is identical to Rattlers'.
UPDATE 03-04-2021: Burger Mojo officially opened 3/3/21 as a 24 hour location. The same day, the Stripes across the street was rebranded as a 7-Eleven.
UPDATE 09-19-2021: Some changes to mention how Rattlers was sold to Sunoco, as well as integrating the 7-Eleven page posted earlier this year.
UPDATE 10-31-2024: Subway closed briefly for a renovation in August 2024. By this time, the entrances have been reconfigured. Only one driveway goes to Holleman now (right in/right out) while a new right-turn only comes in from 2818.

Northgate Shell

Taken by author in 2013.

For many years this was a Shell gas station (609 University Drive), dating back to the mid-1960s with renovations in the mid-1980s (a new canopy, and likely the start of the Zip'N name, as the Zip'N name does not appear in early 1980s phone books). The signage next to University was also the same for years, gaining few updates over the years, like when the Shell logo was updated in the early 2000s before being demolished in the 2010s when University Drive was reworked to be more pedestrian-friendly. An interesting feature of this store is that it has a decent selection of Indian food (Battalion link, archived version); when this began I don't know but it's been that way since at least 2012.
Its time as a Shell came to an end in late 2023 when it converted to Sunoco (similar to the downtown Bryan Zip'N). Gas is usually priced ten cents higher than elsewhere.
UPDATE 01-04-2024: Mild rewrite to account for new changes.
