A quick vanity to all... I am beginning to plan a 1-week or so family vaction (experienced cyclists / hikers) "Up North" next summer to get out of Arizona heat. We are looking primarily at Alaska, Glacier National Park (Montana), Yellowstone. We are looking at hiking, kayaking/rafting, bicycling, horseback riding; and prefer camping to hotel stays. Does anyone have any recommendations as to the best tour company or ones to avoid? Could anyone give pointers on dumb things to avoid or things which really added to their experience? Cheers!
