1. NO. bring all you can drink, if your bringing alcohol into the concert area, it has to fit in a cooler under your seat! Otherwise bring it all! Its BYOB the whole time (accept in the Pavilion)
2. You dig your own fire pits with a shovel you bring. Campfire away!
3. The "campsites" aren't like other festivals, its kind of whilly nilly. If you have a reserved site, then they are sectioned off, otherwise any of the other ones like "main grounds" (which is a cluster, bring a big tarp and come early-see camping line). Or go to overflow where's theres always room and its kind of the same, find a spot, park and go. But yea, its a big field mostly.
4. With each camping pass you get a car pass so 80$=1 camping pass (a tent or camper) and 1 car. You can have has many cars/tents/campers on your "Site" as you can fit. There is extra parking (I've done it, its not far is cheap like 20 bucks for the week.) that is right next to overflow.
5. You can drop your camper off June 24? in the "camper line"...This is usually to get into the main grounds, but certainly can get into overflow too. There's always enough space in overflow (its a big field, they have buses, and its fun to walk around anyways).

Basically, If you want a close site in the main grounds go early and drop off your camper. You have to come back at 6am/7am on the Saturday to get it and find a spot. Main grounds is a mess though, people bring tarps for their friends campers/tents to get enough space for their "site". So plan ahead if you have a big group. Also, its only 1 tarp/camping pass, so bring a big tarp or buy allot of camping passes. (My group usually gets 8 camping passes, with tarps. We usually don't park all of our cars there though. Space is tight in some spots in main grounds.

Otherwise, just show up, find a spot in overflow (or someone else's camper...), park, drink, listen, party, repeat.
