I went in to check that thread because it'll be my first festival in the UK, and fortunately enough, the rules are the same - if not better - than what I'm used to in France and Belgium.
I like, especially, the "no glass" and "only solid fuel" rules, that's quite great. So, I've got questions related to these :
-If glass is forbidden, then can I take a 5l pressurised beer tank? We'll be 4 guys with one big tent and two inflatable mattresses, so we'll be able to carry more stuff than people going alone or by pairs. If not, then we'll just go for the plastic bottle option, not optimal, but still better than going without beer.
-Is it a good idea to bring military rations? The French ones are quite good, there's solid fuel in it to heat the canned meals, and there are concentrated rehydrating drinks as well ; so, I'm debating whether it is actually a good idea, or just gimmicky. Plus, if it is, we'll get to bring our big pot to cook "family sized" meals in it, and it's always a good conversation starter lol.
