Long-Distance Socializing

I'm 24 so I still like to go to the bars.  Not so much the wild and crazy nightclub scene, just your typical twenty-something bars, like Public House or John Barleycorn in Chicago and Features or Blackfinn in Naperville.  Since I'm not on the prowl for a guy but Boyfie lives in Indiana, most of the time I go out just with a girlfriend or two (instead of the gaggle of sorority sisters I was used to in college).

John Barleycorn in Lincoln Park

Public House in River North

Blackfinn Saloon in downtown Naperville

Features Bar & Grill in downtown Naperville

The problem I run into time and time again-- and it happened last night!-- is how to handle when the two or three of us are approached by a matching number of males.  Most of my girlfriends are single, so I don't want to.... umm... block anything but I'm also not interested in seeing these guys once we leave the bar.  I'm a really friendly and outgoing person by nature, so I can't just be rude (or bitchy!) and ignore them outright.  On the other hand, I know they feel led on if I even engage in conversation.

I'm trying to find the balance where I can make it clear that I'm not available without coming across as boring or snobbish!

Does anyone else have this problem?  If you have any suggestions, I'm all ears!

Have a fantastic Independence Day weekend =)
