Patriots Practices: Ticket Policies?

[WaterfallJumper]

Hello, all! I am heading to training camp tomorrow--last minute plans--and I was wondering if I needed a ticket to get in. I know it's free to go, but I wasn't sure whether or not I'd need a ticket for crowd control purposes.

Also, how early should I show up? Half an hour? An hour?

Anyone else going tomorrow? I'd love to meet up with some of my fellow Pats Fans!
