Think i'm to young for warped tour?

Er.
i'm going to warped tour this year i guess :D August 14th..
I'm going with 9 of my friends, and my 17 year old sister.
I hear its a rough crowd, with the mosh pit and shit.
I'm 12, and so are all my friends, were all going no matter what, but
do you think it's a bad idea?
thanks [: xx.
