RE: Best route from Salt Lake City to Jackson, WY
I-15 to Idaho falls, then hwy 26 to swan valley, past Palisades res to Alpine, then Alpine to Jackson! Mostly flat and good roads! Not sure if there is any construction going on, probably!
RE: Idaho fires
We were just north of Salmon and down to Stanley last week and most everything is open! Lots of smoke but some clear days also! Was up to Island Park two weeks ago and the same applied! Fire restrictions in place so be aware!
