I have a friend who goes to this site and he said it is very good. I'm trying to go myself but the journey via public transport from where I live is a pain in the back side and pretty long winded.
This is a very local site been loads times , great site prob averages 150 people a very hard day , building and a jeep with guns , the people at run it are ok , defo worth a visit
I travel from the Southampton area to play this site it's one of the best outdoor sites and definitely run by a brilliant bunch of guys. Especially if you bribe them with cake, any kind of cake there not that fussy
