I visited Reynosa for the first time and went to Boy's town. The cab drivers want $10 for the short ride there and it costs 20 pesos to enter.
I had the cab driver wait for me ($5)as I did not want to walk around looking for a cab later. I went 2 days in a row at about 6 pm on weekdays. It was not so crowded with chicas but certainly enought for me. It would be nice to have access to a shower and August is hot also.
The small rooms all lined up and down the street are interesting with the chicas hanging out as we drove by and waving.
The bars dont open until 8 at night so I cannot comment on them, but they are air conditioned compared to the small fans in each of the small rooms. There is no charge for the rooms like in Tijuana, but they have showers.
$20 dollars for 20 minutes seems to be the going rate and one chica wanted to charge me for extra positions and cbj but another did all for $20. YMMV.

I went back to Reynosa on Jan 5. The boys town was pretty much the same except the pickings were slimmer on a mid week day. $20 for completa. She was one of the better looking ones so I dont know what the others charge. Maybe I will do some research here as I have to come back here in a few weeks. I take the cab directly to boy's town and have the driver wait for $5. It works out well and I dont have to walk around much. Since I am solo I try to stick to visiting during the daytime.
