Any advice...........?

Ahhhh! I dont know how to convince my parents to let me got to warped tour! I already said that I plan on getting a job and paying for my own ticket, but i still need someone to take me (like my dad). I think the main reason they dont want me to go is because of the atmosphere, which is understandable...........but then again its not like im 10, im a freshman. Any advice???
