A few years ago I was hunting in my home state. My hunting partner from CA came up. We used his truck for the trip.
I was appalled at the reception we received when passing other vehicles on the forest roads from my home state. In my truck with my home plates everyone waves or smiles. My fellow hunters wouldn't even look at us. We would wave in passing NO response. We pulled over for two ranchers for a good 5-7 minutes, one on a horse and another in a ATV for their cattle drive, waved as they passed us, they basically looked the other way. We pulled over to let another vehicle pass, as this hunter passes, he loudly says "F&^%$#@ Californians."
I haven't experienced a lot of prejudice in my life but on this trip it was palpable. Needless to say it was a very uncomfortable feeling. This experience changed my perspective when I hear about the story from the OP. I'm sure what he and anyone in this situation feels is 10x more than what I experienced.
