Bar Girls
Lots of good info here. I found the best strategy for hobbying (for me anyways) was focussing on the bar girls. I tried a brothel and go go bars but in both instances you made the call pretty much on looks alone which was ok but nothing special.
With the bar girl option you have a chance to hang out a bit, wait for one that shows interest in you, providing you like her looks, you can chat her up and see if there's any chemistry. If there is then off you go. My experience with this strategy has been tremendous.
Haven't been in a while and I really miss the country. Girls are smoking, country is beautiful and the people are wonderful.
