The name rings a bell but I don't recall the location.
My mall's of memory were the Citadel, of course, and Mall Of The Bluffs when it actually thrived and did a good business anchored by ALCO and King Soopers. All the shops were full and my second favorite hobby shop, Miniature World, was there. Colpar hobbies in Denver was (is) still my favorite.
Regarding Rustic Hills, I remember the book store & theater, The rest is fuzzy though. Seems like there was a sporting goods store there too, Blick's maybe?
Wasn't RuJan hobbies there too?
