I thank everybody for the suggestions and I will use them but where I am going camping I can not bring open bottles or food. I am going to a music festival and basically all I need is a tent which I do not know how to buy.
How many people are going? I know from experience, if, say, four people are going camping, don't get a four-person tent, get one that's meant for six or even eight people. When the tent manufacturers say "sleeps four," they mean four VERY skinny, VERY friendly people, who must also be extremely stupid, because these mythical "people" don't seem to mind leaving their belongings outside, because there's no way in hell they'l fit in the tent with four people in it, lol. Oh, and get a tent with a waterproof fly in case of rain.....don't pitch the tent over moss, because it absorbs rainwater that can leak through the floor, and don't touch the walls of the tent if it rains either.
