It has been about a year since I went. First time was good, there were three clubs in BT, it was late when I finally discovered the best club, I was the only weto in town that night. I doubt that any gringos are going over there now. I usually traveled by bus or rental car on border trips.
Second trip, the best club had closed. Had only one decent club to choose from, and only one hottie there. She had been a star in Acuna, and she had a giant poster (life sized) of herself hanging in her crib (taken while she was working in Acuna). This chick was very hot. I was lucky I got with her and didn't have the whole trip being a waste of time and money.
If you want to know exactly where BT is (or was) google map and find the street on the north end of town called Padre De Las Casas. Follow it up to the streets Fresno, Alamo, Huizache, and Cedro. That is where boys town is and has always been. Any cab will take you there cheap, but only special cabs will take you out (they will try to hit you for $20). I drove a rental car in one time, but it is risky. Everyone is hurting for money down there and more likely now to take advantage.
