How easy is to get autographs at the Van Warped Tour in Atlanta?

[RachaelGrussing]

This will be my first year going to the Warped Tour. I'm mostly excited about meeting/taking photos/getting autographs from bands. I'm just nervous that it would be difficult or what not. Is there any advice for someone's first year and and meeting bands.

[Any other helpful hints are always nice too!]
