85 % of the population in Mae Sot are Burmese. The town is on the boarder of Burma, and thousands of Burmese have fled over the boarder to Thailand. Where they don't receive a refugee status, which means they cannot get a job, any legal documents, etc.
I'm gonna be here for a week - and will visit a tiny Karen village in the bush for a few days, I'll visit one of the refugee camps with a burmese friend of mine, he'll take me to the garbage dump where lots of burmese come every day to find stuff. ETC. I'll be busy.
