I would love to go, I just came back from a week in West Yellowstone, and in August I went to the UK for 12 days. It might be a bit much trying another trip this quick but I could do it. Checking travel it looks like you would fly in to Juneau (11 hour flight for me), lay over at night and fly in to Haines via a local airline. There are several cabins, houses and hotels. It looks like $150 or so a night would get a room. I think four full days of shooting Eagles would be plenty.
My biggest problem is that the wife is an RN, and she is out of vacation days. When we went to the UK she had to take leave without pay and then she didn't get to go to West Yellowstone. She would be mad that she didn't get to go, but she would be happy to see me when I return.
