I-35 & Hwy. 53

This store is actually 60 miles northeast of Austin, and, to my knowledge, the first store in Texas outside one of the four major metroplexes (Houston, D/FW, Austin, San Antonio). Click on the links to see photos of the billboards advertising its presence. If there are any other such billboards anywhere else in the country, I don't recall seeing them thus far in my travels.
