I lived in Leavenworth back in 00-03...there wasn't anything special in the KC area back then (that I recall)...does not mean there isn't now. I had to order from Squadrons catalogue (before I had internet)...until I happened into a Hobby Lobby (back when selection was decent). I do remember a decent shop out in Lawrence. I couldn't tell you the name of it, but I do not believe it was a chain shop though...just a "one off" mom-n-pop type shop.
