I forget the name of it but there's a documentary on Tuck's floating around. I'm sure if you google it you'll find it. It's definitely more of a group atmosphere than any other back country area. I've never done it myself but everything I've ever heard or read is that you should stay away in the winter and go in the spring.
It does look like a good time and PSI, if I can get my back in order and lose some of the lazy weight I've put on over the last couple of years you may have to take me up.
