Let me explain a few things since it seems that you have been on the dating scene about 3 months:
#1 If you have multiple g/f's in the same zip code, they will find out.
#2 There is such a thing as a PKI relationship. They end in, oh about a month (with exceptions) and about all the two get to do is go to Applebees with one of the crews.
#3 and the most important: People at the park, either employees or Season Pass holders, get to see a ton of the opposite gender all day. What makes you stand out (besides being 13 years old, hat sideways, and you holding your pants up with one hand while the other one is in some weird posistion that I know my hand cant get in)
In other words, if you really are trying to pick up chicks on this site, give it up. I dont think they want a punk 13 year old on their hands anyway.
