I graduated with 2 degrees last Spring. After that, I did a semester-long NOLS course to finish up on some credits. It was INCREDIBLE. 94 days in the wilderness? Yes, please. Now I work and live at a lodge in Alta. I said I would go to grad school next year but after getting here, I just want to stay. I'm putting a limit on it though... 3 seasons and then grad school.
Moral: take a year off. Do something awesome. Don't burn yourself out on school just before it actually gets challenging.
