How do you find somebody when you don't know their name?

Ok, I know this sounds really crazy and stupid, but I thought I would give it a try. I was at this waterpark three days ago, and I met this girl. We rarley talked, but every time she saw me she would smile and wave. Before I even got her name or number, I had to leave. I want to see if I can find her, and people say to use stuff like Facebook or Twitter or MySpace, etc. The problem is, I don't know her name. All I know is that she is a female, (Obviously) age and the general area of where she lives, I just don't know exactly where. I would also reconize her if I saw her in a picture. If I don't ever get to talk to her again, I want to at least know her name. Please help?

if you dont know their name, you cant search for her - it's that simple
