 From its original hours back in 1946, it was open from 7 a.m. to 11 p.m. It wasn't until the 1960s that it started being open 24 hours a day. So 7-Eleven. Change it to 24-7. Might be the spot to be this afternoon for free Slurpee Day. It's pretty small. I think we went by there a couple years ago, and it's just larger than a shot glass. But, hey, you know what? You can also grab just a regular one.
