Is this too early to go to Warped Tour?

So Warped Tour is pretty unpredictable about when it starts and ends.
So assumable on the ticketmaster site it starts at 11:00. But im
thinking more 10:30 10:45ish. So is getting there at 8AM or 9AM too
early? What time should we get there so we are the 2-10th person in
line?
