Just found this site, and it's pretty sweet. I thought i'd pick some brains here about something my friends and i are planning. We're looking to drive out west and then stay for a few days in early summer 2011. The first option is Yellowstone. I've only spent one night there, and i'd like to go again.
Glacier National park is the only other option that's really been brought up by the group. I'm leaning towards Yellowstone just because i'd like to see more of it, but Glacier would be nice because none of our group has been there.
I did this in August of '08 by basically going
Cincy -> Chicago -> Badlands and Custer State park -> Cody,WY -> Yellowstone -> Salt Lake City -> Sacramento
The drive was amazing, and i'm tempted to repeat it (except stopping in Yellowstone and then reversing direction). I suppose the big question is "Is Yellowstone better for 3 days, or Glacier?"
