The tranny scene on Revolution has died down. The only main tranny bar is Bambi's between 6th and 7th street, and I also hear maybe one or two others bars might have one or two trannys, but I haven't seen them in those bars. Many times I have the cab drop me off at 8th street, and I check out the REVO bars with a quick peak while I walk down the REVO towards the zona, and all the bars are mostly dead on weekdays.
So if you fear trannys on REVO I would not be so concerned until you accidentally find yourself in Bambi"s. The only other active tranny scene are the street trannys, out off 1st street( ART 123) 3 to 4 blocks east of REVO.( dangerous area) I haven't seen any street girls or trannys on North REVO, but I guess they could be there, also a dangerous area, by Purple Rain.
Craig's list Tijuana, has a picture of a tranny you can't tell the difference, it also has some beautiful girls, and a few of those pictures I just don't believe.( I can't post it, because it's against site rules, but information is ok I believe?)
