Hi Mate,

For green lanes best thing to do is get yourself some land ranger maps. find the routes on them and then get on the blower to your local council and find out which ones are open and shut. I'm only over in Cambridge and the best off road sites close by are Devils pit and Tixover. Bit of a treck but best site i've been to is Kirton off road centre, they do weekend ones and you wont find a better place really.
