Bro YukoOgura, for the Thai ladyboys go to
house 79, it's the one next to the drink shop, 2 shops before the toy museum.
You probably went to house 61 where mostly are Indian ladyboys.
Check out Google maps street view by typing in the exact address. You can't go wrong.
The dotted line on your map - houses with red lamps is the "famed" Desker Road people refer to. These are ladies and a few post op trans that have
official green cards, meaning they have to go for periodic checks for STDs. This is one of the designated red light areas. You're right about the 60s, this place has been around for about 50 years. In it's heyday up till the 80s/early 90s
each and every house you see had women. In total easily 200 plus. The place was packed almost every night. Around the mid 70s you could get a screw for $8!. But time changes...
