Has anybody here been to GNP before? I'm planning a trip there this summer and have some questions.

First, I'm planning a multi-day backpacking trip. There aren't many good loops, so how easy would it be to hitch-hike back to my starting point? Are there enough drivers around that I could plan to end a trip 20 miles down the road from where I started and rely on hitch-hiking to get back? It looks like one road has a shuttle, but other than that idk.

Also, what stuff is there to see except backpacking? When I went to Yellowstone I ended up doing only one night of backpacking because there was so much stuff to see driving around and doing day hikes. Is GNP going to be a place that I'll want to do a lot of driving around for side-trips?

Finally, is there any other cool stuff I should check out in Montana or around that area? Never been before, wondering if I should spend a whole week in Glacier or do a day or two elsewhere in Montana (I'll be driving to/from Colorado)
