Funny, you seem to have had a better selection of Trav material way up there than we did in Cincinnati, which was basically just down the road from GDW (though I’m completely ignorant of how/where they printed and shipped, markets, etc).
We had King Authur’s Court, a boutique hobby/games shop which carried quite a bit of TSR products and the limited selection of Trav I mentioned above. And Dragon magazine.
By ‘86 we had D&D boxed sets and AD&D hard backs in the local department store toy sections and book stores, with Star Frontiers, Gamma World and other TSR games filling the shelves in the hobby/game shops. Still precious little Traveller tho.
A tangent, my grandmother found an AH game called Luftwaffe that she got for grand dad one Christmas but he wasn’t interested in it and gave it to me. Couldn’t find AH games anywhere until we took a trip up to Wright-Patt in Dayton and I scored Squad Leader and my buddy got Panzer Leader. RPGs took a back seat for a while, especially after we discovered Military Modeller magazine and Tamiya 1/35 scale WWII models.
Good times.
