I'm planning a round trip from SF to northern Michigan next August. Going east I thought I would take a northern route through Idaho, either entering from eastern Oregon or coming up from Reno. I'd love to know what routes this LF crowd might recommend and what areas you think are really wonderful to photograph. I would guess I should plan on going as far north as Glacier NP :-). I'm bringing both 35mm & LF so I can photograph wildlife & landscapes too.
