Peach Music Festival (Pennsylvania) Ever been camping there?

It looks l am going to this year’s event and am curious about a couple of camping things. First, how early do you need to get there in order to get a campsite that is not on a steep hill? Second, is “bring your own beer” permitted in the camping area? I’ve been to fests where it was, technically, prohibited but all you had to was make an effort at hiding it at the gates and there was no problem bringing it in. Once inside, no enforcement except in the case of really drunken behavior and that was almost always the under 21 crowd.
