TENT - at least one man bigger than you need, you need to keep your beer and clothes somewhere.
Army tent/gazebo - If one person in the group can bring this, it will give you somewhere dry to drink and socialize when not in the arena.
Sleeping Bag - Good idea unless you want to get cold.
Mat/air bed - makes it more comfortable
Pillow - I just put a fluffy jumper over a clothes stuffed rucksack.
Food -Can be bought in the camp site although quite expensive. can be bought cheap from town centre.
Cutlery- Turns out to be useful
Camping stove - If your planning to make any food, you'll need a camp stove or disposable bbq.
Pot - if your using a camp stove, then you'll need a pot to use on it.
Comdoms - Be safe or may come home with a funny itch!
DRUGS -Enough said OH wait
(as in Asprin, pro plus, plasters)
Matches/Lighter - Need to burn things. It's a must....
Hammer - Those bloody tent pegs never go in.(don't think that'll be a problem this year.
Small Knife - Like fire it's a mans essential. Useful!!!
Torches - Un-less you've been bulking up on those carrots.
Batterys - Power those torches and other equipment
mo3 player/speakers[/b} - again if one person in the group can bring a MP3 player, then all is good.
Bog Paper - Very Important,, Will be a messy weekend without as all of the paper in the loos gets nicked or runs out
Boots/Wellington boots - The camp sites are still very wet, this is an essential this year.
Cash - 50+ ( I budget 50 a day)
Camera - Best taking a disposable one or a cheap digital which you don't mind losing.
Sun tan lotion - It can be quite hot. Hopefully we will need it, but doubt fall.
Jacket/Coat/Poncho - I take a poncho, small easy to carry/put on. Great festival image.
Sunglasses -Handy.
Deodrant -You will Smell BAD after 1 day of moshing etc..
toiletrys - Tooth paste, wet wipes (can have a wipe down everyday, keep that smell at bay) etc
Beer/spirits - What's a festival when your sober. Take plenty, leave in car. Then you can go and collect rather than walking into town, which have sold out.
Friends - Don't forget to bring them, especially if your driving
Extra clothes - Your clothes will get wrecked and lost bring some more
Warm Clothes - It can and has got very cold at night, remember you'll still be up at 3-4am and much much later. Brings Loads of warm clothes, layers is the way forward. Layer up and it traps the heat in. Jumpers, coats. make sure you can fit one pair of trousers over the other to keep legs warm. Gloves!!
Soft drinks/collapsible water container - You will get very very dehydrated, beer + moshing = lose.. So make sure you either bring loads of soft drinks, or a collapsible water container, you can fill up from a water point.
Bin liners/carrier bags - wrap bog roll, clothes etc in them. Stops it getting wet, aslo can be used as bins.
Chair - I think it's essential, You've been stood up all day. You need to chill out and relax. more comfortable and can be kept dry. Unlike the floor.
TICKETS - you wont be doing anything without them. (due to my friend losing my ticket in 2007, don't let tickets out of your sight either.)
