The day we entered, our desired campsite was occupied by a group led by Rabbi Moishe Kasowitz, a Lubavitch shaliach from St. Paul. After declining my offer of a Bud Light (the Rabbi only drinks REAL beer), he still invited us to claim the site when his group left the next day. Kasowitz leads groups annually through Inward Bound. http://www.ib.org/bwca/paper1.html
