I'm 15. Is it safe for me and 3 other friends to go to Bamboozle?

I'm 15 and 3 of my friends (1 of which is 16 and the other will be 16 4 days prior to the concert) and I want to go the Bamboozle Roadshow this summer. My mother is concerned that it's not safe. I'm pretty sure it is, but I just need help convincing her. Anyone got any reasons why it's safe?
