The study abroad program is good - I didn't myself, but we had people all over the place. I've heard that Kalamazoo is a major study-abroad place, and I think Knox might not be quiiiite as good - but it's decent!

Internships are a major yes. They can hook you up.

And I totally have no idea about rock climbing, though I wouldn't expect there to be much, since it's in such an expanse of prairie flat!
