TrevorK: GOOD LUCK!
Girls are evil.
Honestly, you can meet girls anywhere... but getting out is definitely a help.
My first girlfriend I had met fencing... but only started to talking to after I got her phone number from her exboyfriend. Turns out he must have been REALLY pissed at me -- a lot of the less-than-kind descriptions of girls I've seen here remind me of her... took me two years to learn, but still... I was in high school, okay??? I learned when I went to college.
The next girl I met when I was walking back from class and had stopped to talk to a (female) friend. As the girl (Sarah) knew the girl I was talking to, she was introduced to me... and then Sarah told me I had to come by her room and fix her computer. Yes, I'm serious. I ended up asking her to dinner (I didn't intend it as a date, just commented that I was going to a restaurant in town, and then invited her... it worked, okay? )
After that relationship failed, I met a girl at play tryouts... I didn't get a part, but I found out she lived four floors above me in the same dorm. A week's worth of talking (I had a bunch of people die at once, so I really needed someone to talk to) and she was mine. :] Yeah, okay, so that one failed to.
I met my current girlfriend (by far the best of the bunch) in a manner similar to the first. I was going to lunch, and saw a friend studying for a test. Went over and talked to her, and the girl sitting next to her introduced herself to me. I ended up talking to my soon-to-be gf for five hours that night (via AIM, and then on the phone), and then talked to her every night for the next two weeks -- which was tough, it was the end of the semester, so I was calling California from New York. When I flew out to Redmond to work over the summer though (yes, for Microsoft... I may not love them, but the awe I get when I give people my resume now was worth renting out my soul for a while... And the free soda is GOOD), I stayed at the airport to meet a plane from California... a lot of hand holding insued before I even asked her out.
So, in summary, the keys to meeting girls are: have friends and talk to them, go out and do SOMETHING so that you'll have something interesting to talk about, and talk to whoever you're interested in -- take the time to get to know them. It might not lead anywhere immediately, and may not ever. But I only knew the girl who introduced me to my second girlfriend because I had talked to her throughout the previous year... when I had a rather major crush on her. See? You'll still profit.
Good luck again!
