When I read your original post I assumed that the track at Orpington had closed....
There is a track about 30 or so miles from you near Ringwood, Dorset
http://www.southcoastrc.co.uk/ the next nearest track that races largescale is Sweetnap just south of Frome on the Somerset/Wiltshire border
http://web.me.com/jmcmanus/Sweetnap_Raceway/Welcome.htmlI'm trying to get the landowner at the Angmering Motorsports Centre (just off the A27 near Worthing, Sussex) to commit some resources to rebuild the old 3aRaceway track for use by the largescale cars. At one time it was ideal for bashing -


The track layout has been simplified and the rostrum removed but with a little work it could make a viable location for bashing/racing and there are few restrictions on the use of the site as well...I don't recommend travelling down to use it at present though.
I hope you sort out a new site soon and please keep us informed and I will try and come down.
