I been saying for a while the northern girls are good < especially that side. Chang rai, itself has a beer counter in big C that uni girls seem to serve up jugs at. The westerners are sparse so youll snatch phone numbers very easily, and later its all good. But I can vouch alot are very keen to keep thier mans attension. cheers!
