George, After a lot of prodding, I finally added a blog at www.bestofthetetons.com. If you are coming here, you might want to check it out. I write it as a guide to both photographers and tourists visiting the area from the perspective of a long time resident (26 years). One of the recent posts was titled "If I Only Had One Day In The Tetons".
Obviously, GTNP is my favorite park, too! Hope you get a pile of winners while you are here.
