I'm not finding these girls hardly ever. I mean sometimes I'll see a really attractive girl with just one female friend, but they're always being gamed by other guys. A lot of times the staff and bouncers of the bar. Maybe it's just my experience where I'm at, but I'm pretty sure most of their time is spent hanging out in a "social circle" group. Sometimes towards the end of the night when her friends hook up and the group disperses you can go in. But I find guy groups gaming them at last call and out the door and on the street. I lost more than one girl before to a group of guys going after even outside the bar. Another thing is I notice the hotest girls leave the bar prior to 1:30am, prior to the 2am last call. Whethr they leave with guys it's too chaotic to tell.You can find plenty of girls who don't group and gossip.
I agree if the girl is attracted things can happen a lot easier, but when you have to get through a sh!t fest to get to the girls in the first place, then you're relying mostly on your looks.
