When you are in Chiang Mai or anywhere else in northern Thailand check out some of the hilltribe villages. You can hire a guide to take you there. Alot of the hilltribe villagers will try to sell you little trinkets or handbags. It’s nice if you buy a little something from them even if you don’t want it all that much because these people are really poor and tourists are one of their only sources of cash. And don’t bring any drugs with you or back with you! The cops often stop and search tourists coming back from the villages. Besides, you shouldn’t contribute to the country’s drug problems.
