There are a few: Hailey / Ketchum / Sun Valley is the first and worst; Moscow, where I work, and they're starting to infiltrate Coeur d'Alene and Sandpoint because those are resort communities full of amenities for the well-heeled. Usually they don't last through the first winter.
We're discussing levying a bounty, if we could market liberal-hide belts and hat bands.
