Ah man, I drew up a huge list of stuff for Nozstock for me and my friends as a means of wasting time and it's looking like a smart idea now that it's getting closer to the time! Being prepared for anything dodgy makes it much easier to enjoy yourself because you know you don't have to worry about anything.
Basics
Tent - Pretty new-age thinking, but yeah.
Sleeping stuff - People often underrate the importance of a good rest at festies. Roll mats, pillows and sleeping bags for sure
Food and cooking - Either a little camping stove and buy the biggest bag of pasta known to man, or we just buy hot food from various stalls there.
Money - It is highly likely that we will need to spend money there, as a result, we should all bring money. Crazy, I know.
General campsite equipment - We will need some chairs, maybe a table and some fun things like a frisbee or a puppy that will bound about and make us laugh.
Phones - It's not unfeasible to say that we might lose each other or our tent at some point across the weekend, because of this we should all make sure we have our phones with us. Use them sparingly though, as there isn't a chance in hell we'll get them charged. That means switched off when sleeping and pretty much whenever they aren't in use.
Clothes - As much as we will try to deny it, there's always the possibility that we'll get rained on. That means we need wellies/coats and warm ****. On the other hand, we could have a beastly scorching weekend, in that case, it's shorts and wife beaters at the very most. Just be prepared for any eventuality, essentially. I'm not gonna waste my time creating a giant clothes list... (I may if I remain at this level of boredom). Also, fancy dress/hippy dress/funny outfits in general are a MUST. A MUST GOD DAMN IT!
Drugs
*whatever may tickle your fancy, I feel TSR is not the place to divulge further info*
Drinkies - I'm quickly coming to the realisation that drinking is one of the worst things to do at a festival. It's expensive, takes more effort than most things and is a downer anyway. You drink it, it's a depressant, and then you get sleepy. Be that as it may, it's always nice to have some cans around for the daytime to just help maintain a bit of a buzz.
Medicine - Logically, following the drugs section, we need medicine. First up is:
Paracetemol - Nice to clear away any headaches and I doubt it will kill us if we mix it with dangerous drugs.
VITAMINS - This is what I reckons is key. If somebody is doing a certain inhaled dissociative, it's important to replace the Vitamin B12 that it cuts off/restricts/replaces (can't remember the science behind it). On top of that specific one, keeping a healthy immune system would be nice. Nobody wants to be vomiting out some random ass illness on the second day of us being there.
Strepsils - I know this after having a throat of fire on the Sunday night of Aeon last year, smoking like **** can hurt your throat. Madness. These might just help a bit.
Other things that can get overlooked
Water bottles - Hydration is ****ing key to going on a three day session. THAT, my friends, is why we need to take bottles so we can fill them up from communal taps whenever we're running low. So damn vital.
A torch or two - Might seem a bit silly, but this way we don't have to waste battery when using our phones to stumble to the tent or to a toilet in the middle of the night/morning. Not absolutely neccessary, but they'd be sensible.
Wet wipes - Just in case someone has an accident. Hahaha, no but really, they're really useful for just cleaning the grime of one's face or just if you need to wipe anything. Multi-purpose, cheap and could be a godsend.
Toilet roll - Never know what we'll face when we're in there - some festies are famous for having amazing toilets but others may well be a culture shock. No harm in being prepared.
Bin liners - Useful for... Well, storing stuff in. Be it empty cans/cannisters/butts/anything or wet clothes, I reckon they could be bang tidy if we had them. It also means we can clear our stuff away nicely - they're holding the festival for us, we may as well save them a tiny bit of clearing up.
Toothpaste + toothbrush - Just... because.
So yeah, that's pretty much copied and pasted, but I think it's a pretty good list. Made from various experiences and advice along the way.
