the only proper place in london is in enfield. its behind chase farm hospital. got a few lines of dj's, big set and small set, lots of north shore, freeride jumps, and small dual slaom track. might be heading up there this saturday.
yeah the overground from new southgate to gordon hill. about 20 ish mins. i didnt know about the bmx track in hackney till yesterday. deffo worth a visit. looks great fun!
