Dont know if its of interest but we run a weekend every month at Shottle, near Belper, Derbyshire. The sites superb and was the rover owners national event site in the 90's and its been well expanded from then. AWDC use it as well as the local Landy Clubs.
Its not normally open to the public but we've struck a deal with the owner to allow us to offer it either single day @ £25 or the weekend for £40 inc free basic camping thereby passing the benefits onto other offroaders rather than them paying through the nose.
If its of interest, theres more info here: http://www.shottleoffroad.com. Next dates are 21st & 22nd July.
If anyone wants to see some pics I can post some from the last event on here
