I'm up in Sandpoint, and there's a couple of other Mopar guys in this area.
There are allegedly a few Mopar guys in Coeur d'Alene, but I've only met one years ago.
Got a buddy in Meridian, Mopar guy & member here, and there's a fair amount of car culture around him.
Got a great drag strip in the area.
Mountain Home looks like a nice area.
Idaho is definitely not "west coast" in any sense; most of it's a lot like going back in time.
