There are several. Near Whitefish, MT lives a fellow named Jim Smith that has quite a collection at his private strip. Mustang, Corsair, even a Seafire; complete with a griffon engine and contra-rotating props; and several more. The owner of SemiTool out of Kalispell also has a really nice Corsair. In Bozeman you'll find a BT-13, a really nice AT-6, 3 L-19s, a CT-133 (frostback version of the T-33), a Mk. VI Sabre (frostback F-86), and 2 F-100F Super Sabres. There used to be a Mig-21 based in Helena, but it hasn't been there in a while. Also, the tech school in Helena has a few relics laying around. Their F-89 Scorpion was just dismantled and moved to a museum operated by Bill Anders (the astronaut) in WA state. They have a MATS Super Connie that has been the topic of many a restoration discussion as well.
