My good friend and backpacking buddy is going to be starting med school in the fall. We'll have about a month in the summer for one last adventure before he takes off so we're trying to plan or at least get an idea of where we would like to go. I'll be meeting him in Dallas around June. I've looked through Matt's list and found some great ideas and I've also read through the best places in america thread to get some good ideas. I was just curious if anyone had any other must see/do adventure ideas that weren't listed or mentioned in those threads.
