While I've got a pretty short commute now I've been lucky as the last few weeks the treasure valley in Idaho has been stuck in a nasty inversion (google it if you're not aware). The air in boise is heavy and wet and every morning and early afternoon it's been "snowing" which is basically the atmosphere freezing and falling, and not to mention foggy every day during it. This is the time of year I get a bit fed up with riding as the all the pollutants in the area just sit in the valley and don't move trapped by pressure, it's been a while since I've seen any studies comparing the boise air during inversions but I'm assuming it's really bad.m any other valley livers stuck in crappy air?
