visited Pittsburgh once to meet M.Fitchenmeyer (sp?) and go to one of his hobby meets - sheesh, probably 6-8 years ago. visited a shop there, but can't remember the name..pretty sure it wasn AB Charles (mine was an older one-story shop). shop was on a street that was on a hill and the store had tons of roco. i wasn't into SS modeling yet and had no idea that these little tanks would play a part in my future collecting...but was def'ly in awe of their assortment. store overall seemed nice too.
That would have been AB, it was only maybe 2-3 years ago they moved into this new building, old one was supposed to be demolished for the car lot to expand that was nearby but last time I was past it hadn't happened yet.
