The sun doesn't set here until about 2100 hrs; northern latitudes are great. I had time to take a scenic float down the Snake river. Saw a LOT of wildlife. Well worth the money. We saw bald eagle, moose, elk, deer, beaver, sand cranes, pelicans, and a bunch of other birds. This is a "Must Do" if you're in the area.
This has been an awesome trip. If you've never been here, I highly recommend it. I posed more pictures here:

In mid July, the days are mostly pretty warm. It's only in the mid 80's, but the sun is intense at this altitude. You'll work up a sweat if you're hiking or boating. But once the sun goes down, it cools off fast. Again, clean thin air doesn't maintain heat well. it quickly drops to 70. When I leave in the morning it's in the mid 40's.
I was here about 10 years ago, in Feb. All the elk come down out of the mountains and spend the winter on the preserve. Which is a big flat open plain at the bottom of the valley. The Elk Preservation Society will take you out into the preserve in a horse drawn sleigh. The elk are so close, you can actually reach out and touch them (they ask you not to).
I'll have to plan to come here again. I think there's another conferance here in Sept.
