Top:with trecking buddy in Changmai. we explored 3days2nights over mountain. leech, elephant, mango, rain, village, pig, cow, afternoon, plow, night, darkness, airplane, opiate addict...it was a good adventure anyways. Bottom: a snapshot with minority group in a very small villege. we saw their life, and we knew a bit of them..that's it. sometimes to know something is more important than to do something.
