myself and a few friends are going to be driving through montana, and were going to camp in glacier for a few days. we're looking to go white water rafting, and my question is: where is the roughest, best rafting in that area!!! i have gone rafting and kayaking before, and would like to show my friends a thrill that they won't forget, so i'm looking for the best, most thrilling adventure! all options wil be considered, especially bodyboarding! i can't stress enough that i'm looking for a thrill!! we want a challenge!! also, any ideas of areas to camp around glacier will also be appreciated (especially cabins). thanks alot for the help.
