I can tell you from my very own experience a few weeks back, Idaho is a totally different beast!
It appeared as though once the sun set or so it finally got good for winds, weather, etc., but.... mornings are much preferred. It went from 60 degrees at 9am and then 85 degrees at 10am...."DENSITY ALTITUDE" went through the roof in a matter of an hour!
I fly in density altitude daily here in the Sierra's and have flown all over Alaska into crazy places landing on the sides of mts chasing sheep and other critters.
Seeing the strips in Idaho you better know your surroundings. The strips there are in places that will blow your mind. Seriously! 9000' peaks with really tight canyons and the strips are at the bottom around 5500' or so. Just know before you go and give yourself the option to get back to McCall in the event your conditions do not allow for landing later in the day. JC is much better to get into than Big Creek, but its still one of those Idaho LZ's. Great spot, just know before you go.
Conditions in the bottom of the canyon may be totally different than at the tops of the canyons as well. That also mean downdrafts that your not aware of until your deep....
Be careful!
My confidence got the best of me.
