There are a few parking spaces available between the Taqueria and Patriot Plaza.
If you're travelling south down I-35, this is a relatively easy (although potentially frustrating), stat boosting, P&G for you. Just exit 294A, grab it, and get right back on the Interstate.
Just a helpful note... this cache is in Bell County. Since many people like to fill up their county maps, this could help you to achieve that goal.
Lots and lots of muggles in the area... the Taqueria is a pretty popular place. Just be cautious, and please put it back as you found it. Also, it's super helpful if you put the log in the cap before twisting the container back together.
Happy caching!
