have fun.
i don't hang around areas where u go to.
those people go to where you tourists go to.
I don't even go Thailand, I saw some "pretty Thai women" in
Singapore, not even redlight district.
You think that these transgender will only stay in redlight
district and they can't go shopping in orchard or go watch a movie
or supermarket or hospital?
Just becareful lor, you might end up like "the crying game".

With Thais it's still good to practice a level of caution.
