Anyone ever participated in one of their wilderness excursions? DH is reading "Miracle in the Andes," a book about a Uruguayan rugby team whose plane crashed in said mountains in the early 70's. (You may have seen the movie "Alive" that was made about it.) Anyway, it got me to thinking about "getting back to nature" - although not to that extent; what those guys went through was horrible. But OB came to mind. We're big skiers, and I found an 8-day off piste (back country) ski trip that they're doing in February in CO - which happens to be right around our anniversary. I've never gone 8 days without running water, and I know that the physical challenge is incredible, but supposedly it's life changing. Has anyone had any experience with OB?
