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.
