There is a Verizon store adjacent to an Att store on Howe Ave. here in Sactown, and Verizon's store is always the busier of the two. By the by, the 3g coverage map is in the window of Verizon's store. -- The weekend is here, grab a can of beer!
There is an AT&T store near the Verizon store where I live as well. The Verizon store usually is much busier. That's why I like going to the AT&T store - I won't have to wait a half hour in line just to see a rep. I walk in and get service right away AT&T.
