Well funny thing about that. I live in Monroe County which is the county on the eastern end where Rt80 comes into PA. Currently there are NO hobby shops in Monroe County and the only one in PA that I go to here and there is down towards the Lehigh Valley, Trains and Lanes, but they rarely handles Tamiya, just traxxas, Armaa, and axial, plus lost/associated for the race guys.
So, earlier in the year, I found a hobby shop just over in NJ, F&M in Flanders and he has tons of Tamiya kits. It only takes me about ten to fifteen minutes longer to hit the place in NJ but it's worth it. He even handles Kyosho kits too. He has plenty of stuff for the traxxas/aarma/axial crowd too.
