Glacier National Park

My 2007 summer vacation destination! Tim and I are roadtripping to Glacier Nat'l Park for 10 days this summer. Backpacking, camping, fly fishing, seeing moose, maybe white water rafting are all on my agenda! I do not...however...want to run into a bear while I'm at the park! The more I read about Glacier, the more I see about encounters with black bears and grizzley bears and bear safety...hmmm...I might need add pepper spray to my "to-bring" list! If anyone has been to Glacier Nat'l Park, please let me know of any "must see" attractions!
