Let's be clear: these people are not our kind of people. If they didn't have something to complain about, they'd have nothing to say at all. Yellowstone National Park has experienced early season high traffic, followed by historic flood damage this year.
It seems to me, and I could be wrong, they are kind of a Montana tourist thing. Not that locals don't enjoy them, because they do, but it seems like every time I see them, it's either in the Airport in the "Montana" section or in the "Montana" section of the grocery store or a local gift shop.
