Incidentally, the children in the pictures below are wearing traditional Karen fabrics. The bicycles were donated by the government in this case; sometimes schools like this get bicycles donated by NGO's.
Most importantly, I noticed that the kids had pretty good teeth. This is exclusively due to a government program of routine visits by traveling dentists, and another government program of providing free milk to grammar schools on a daily basis. These are both recent developments. When I first got to Thailand, kids at out of the way schools had horrible teeth and the programs were just getting rolling. So, progress of a sort.
