1. Stick your head out of the tent every now and then and call out "shhhhhhhh". Probably won't help much though.
2. Drugs, ear plugs and 2 pillows to make a head sandwich. You'll still hear drumming all night though and will wake up grumpy and irritated and generally hate the weekend.
3. Go with the flow. Act like you're 20 again, party til 3am with your neighbours then sleep for 3 hours. When you get to the festival, find a nice shaded area and a chill band, buy a $12 beer and kip for an hour or two. That way, you'll only have yourself to blame for your sore head and general exhaustion and you'll be way less grumpy!
Last year we had to leave on Monday and although we were majorly boxed in, there were enough others leaving that by about 11am, room had opened up for us to get out. I'd expect the same again with the number of Canucks that go down there not having a Monday public holiday.
Can't remember if they do a pat down but they definitely search bags. It hasn't stopped me getting booze in but you need a bag with a good hiding spot. Also it pays to make their job easier by coming up with your bag open and take a few things out for them. Makes it look like you aren't hiding anything and they'll be more likely to wave you through.
Sorry I can't be assed reading all of this thread so excuse me if this has all been said before. I've been for the past 2 years and a couple of tips for newbies. Most importantly, weed related: 1. There are occasional cops that wander the camping section. I almost got busted 2 years ago chopping up a big bowl when 4 cops wandered past. Same goes for in the venue itself, although I think they're security guards, not cops. I had a security guard try and bust me for smoking a doob in the venue last year, but I told him staight faced that it was tobacco and he left me alone. 2. Security at the main entrance is pretty thorough. They have previously searched my cigarette pack looking for doobs, no kidding. If you smuggle alcohol, get creative. They search bags pretty well. If anyone expects another Pemberton you're in for a big surprise. 3. The walk to the venue from the campground is pretty long so take enough supplies for the entire day. Also, make sure you remember an easy way to find your tent before you leave. It is crazy hard to find again at night. Camp near someone with a massive, distinctive flag. There are a fair few. 4. Don't expect much sleep. The camp ground parties all night, so plan for a big party and noise til 6am. If you want to sleep, don't forget earplugs and a pillow (or 2)! 5. If you see a washed up drunken Aussie wandering about, say hi! And offer me a doob!
