This well was on the roadside on the way to Cerro Negro, Nicaragua for volcano boarding.
The oxes just go and go. I finally had to trim the film at flickr’s 90-second limit.
That reminds me I should have pointed out that the various tour operators can combine volcano boarding with nearby village school visits and/or hikes to lagoons for a swim. Moon Travel Guides has a good list of operators, I went with Julio Tours and was happily satisfied.
