Insomnia
TWA woodland is absoulute murder for the "call your hits crew" they'll be hitting shrubs or you're well out of range oblivious to them. Tell your son not to worry about it, I've stopped attended the sight as it was not much good to begin with but just descended into even more squalour, the good marshals left because the owner runs his business in a very silly way that doesn't make much sense. Theres a few people who are twats too but you can't fault most of the regulars. It was mainly the site layout that caused me to stop attending, it was just too repetitive, no good firing points, if you're in a building you're set to die etc.
Also, it's not even the nettles, its the 2 inch thorns on them lol!
