What September feels like
The valley goes amber, the cottonwoods along the Snake go yellow, and Old Bill's Fun Run raises money for half the nonprofits in town. Pack for two seasons in the same day, because the mornings have gone properly cold again.
Expect about 4 days with real rain — enough to notice, not enough to plan around. about 15 nights dip below freezing.
