Unless you're tried as an adult, which you won't be, then your juvenile records will be wiped if you request it. Maybe even if you don't request it, but in my state anyway I did have to request that my juvenile record be wiped. Yes, I was a juvenile delinquent, had a document that had that stamped in red in giant letters on the front. The reason was incorrigible, as my guardian (my grandmother) just couldn't control me.

If you make a habit of this type of stuff, they can take you away from your parents and throw you in a juvie work camp deal until you're 21 (again, that might be state-specific). They threatened to do that to me, but I joined the Army and escaped their clutches.

If that's all you do though, you'll be okay, and I wouldn't sweat it too much. It'll seem like a big deal for a while, but it isn't.
