yeah bars/clubs are not that bad, best if they have quiter areas, sofas etc as well as a dancefloor, but a lot of people find them intimidating (cos of the loud noise, big groups etc), which makes it even easier for the boys who arent intimidated.
Otherwise, anywhere is cool to meet girls. they like boys. they want you to talk to them and show them what a great person you are. they like sex. they want you to sweep them off their feet and then take them home and pound them into the matress until they cant remember their own names (dont take me too seriously, obviously girls dont necessarily want to be approached; they mite have a boyf, they might have other things on their mind etc, its just a good mindset to have if your looking for someone).
