I'm hosting a party at an hour away from where we live and I tried to invite as many people as I can. But Currently, I got a ratio of about 4M:1F. I don't really have friends that are women anymore and women I know do not have women friends (or interesting one at the least). I really want to find a way to make this ratio 1:1.

One of my friend got an idea, but that sounds like a plan to trash the place. The idea would be to post an invite on a page with lots of girl (like on the psychology students group of the university). I'd like 15 more people at most and I guess that might bring much more people that that.

Any other idea?
