We all payed £10 each deposit a couple of weeks before hand (payed on my brother in laws card) then just £25 when we got there,
It doesnt need to be serious

it's all just a bit of fun,
when i was there a few weeks back, it was totaly pissing down, and it was the best fun iv had in ages!!
your right about the top and bottom corners hoshy, there mint in the wet,
flat out, sideways, cant see anything because the visor was muddy as hell, had to drive about with it up for quite a while, my face was just coverd in mud, and i was just laughing away to myself inside my helmet
it's great!!!
