I've stated before that my soul resides in Western Montana. My '95 I heard all the tales of how Montanans disliked Californians, and their big money that was buying up all of Montana's land and erecting massive log homes and creating new ranches. Went there, regardless. Drove 1200 miles through the Bitterroots, up to Kalispell, West to Troy, then turned back East to Seeley Lake. Beautiful!
Anyway, in the process of stopping in at numerous reality joints it quickly became apparent that none of the agents and their hired help were native Montanans. Of the two agents we dealt with, to buy our Seeley Lake property, the listing agent was from Oakland and the selling agent was a New Yorker. The owners of both the RV campgrounds we stayed in were originally from Southern California.
In the end, though, it wasn't so much Californians they disliked, it was the hordes from Seattle.
