Grew up in Berwyn in from the 1940's to the 1972. My local hobby shop was Winsor Hobby Center on the corner of Winsor Ave and Clinton, across the street for the Burlington tracks. Spent many hours there and many dollars as well. The owner, Bob (don't remember his last name) was a great guy and always willing to help me.
I now live on the west coast and do miss certain aspects of the old town: White Sox, Blackhawks, and the CB&Q. Don't miss the winters.
Good luck and continued success to you guys at Berwyn's Toys and Trains.
