I am tempted to participate in the gathering and would like to make flight reservations now, or soon as I will be using some of my frequent flyer points and the longer you wait, the less lukely you are to get seats. How certain are the proposed gathering start and end dates?
The dates are pretty much set in stone enough that you can go ahead and make your flight reservations. Don't rule out the idea of flying into Salt Lake City, especially if you plan an extended stay here in the states or are having trouble getting a seat on a plane flying right into Jackson Hole.
Sit tight on Lodging though. I'm researching things now and will continue to make announcements on Lodging options as well as more information on local discounts throughout the month of August.
A horrible snow year is the only thing that will change things.
