I have, i went backpacking in Montana. My parents made me do it, maybe they have fun ones, but the one i did sucked ass. There were these three black girls on it from Jamaica-Queens, who got some kind of scholarship and were on it, and they they fucking did was complain. They couldn't carry the whole weight of their backpacks either, so we had to split their shit up and i ended up carrying a ridiculously heavy backpack because i was the only one on the trip in semi-decent shape. When it was over, i guess i was glad i did it, but i would advise you to avoid Outward Bound backpacking trips.
