If you are interested in working in one of these hill tribes as a volunteer English teacher, please email me and I will be more than happy to help arrange an opportunity for you to help. I am constantly being asked by school directors if I know of anyone who would be willing to come here and teach, as there is a huge need for English teachers in this area. If you're looking for a way to experience Thailand in it's true form, rather than through the eyes of a tourist, this is the best (and least expensive) way to be able to do that. I am in contact with schools ranging from the most remote areas to right in the center of Chiang Mai, so regardless of the level of "roughing it" you're up for, I can find a place for you.
