Yeah thats good advice about the helmets LOL they are seriously rank, you wouldnt wanna put your hand inside them, let alone your head! If you wanna go 1/4miling for the first time, best to go when a few of us are going along anyway, and youll see whats what when you get there. But basically its as Jon said above. If in doubt, at York theres a sign on hut. Just park up where everyone else is, then go in the hut and ask what to do and theyre very helpful.
