How to find someone I've met once?

[H]

So yesterday at an amusement park, I was with two of my friends. We were going on a 2-seater ride, so I sat in the row behind them. I was sitting with a guy who looked about my age. He was also with two of his friends, but they went in the cart before ours. He was very nice, and we were joking around. However, immediately afterward I regretted never having gotten his name. The rest of the day I tried looking for him, but the park is very big and I didn't see him again. So, is there any way I can try looking for him? For instance, is there any way I can look through a list of the facebooks of people aged between __ - __ in the state of _____? I know that this would take a very long time, but I'd like to try. All I want to know is if this (or something similar) is possible.

You can't, but try to search him by place. You can filter on a search box.

Yeah, you can check by the place he lives but it'll be a pain in the ass.

That's kinda creepy, too.. no offense.
