I can't resist a quick anecdote about the Buak Haad park with a good story a friend tells from quite a few years back.

He was sitting in the park on Christmas day enjoying the surroundings during a pre-lunch stroll. A monk accompanied by a young guy (Hill tribe IIRC) approached him and struck up a conversation. It wasn't long before the monk came out with his real purpose which was pimping the boy. I'll leave the story hanging there as I know you guys have vivid imaginations . Amazing Chiang Mai - never a dull moment which is why I like living here.
