We don't really have much beachfront property in Montana, though I've seen plenty of naked folks in the rivers.
Montanans are intensely private people and proud of it. I have never heard my gay friends mention being unwelcome, though I'll certainly not speak for them here. I've never been stopped drinking beer in a park, though yes it isn't legal in my town (although not true of all towns in Montana like Butte). Sorry that you can't smoke a joint in a cafe right now, however you can pretty much smoke it anywhere else in public so long as you don't bother others.
I'm guessing Americans that moved to Holland are probably pretty happy there. That says absolutely nothing about the United States.
