The region in which I was working in rural Bolivia for 11 weeks had a lot of attractive locations. Indeed part of the zone is now a national park due to its natural beauty. The Surutú River passes through, and one day I needed to get across the visit a school on the other side. The river is “young”, in that it isn’t settled in a specific bed, and since it can change course easily, there is no value in building a bridge. The only solution is to pull off your pants, hold them above your head, wade chest deep to the other side, then get dressed again. It didn’t always work perfectly. Once I slipped and dropped my pants in the river. Luckily someone downstream caught them for me, or I would have been one embarrassed education visitor.
