Autocar magazine are running a 2nd offroading day at the Eastnor Castle Land Rover Experience on Friday 2nd December, and you don't need to use your own car for it other than for getting there and back. Pity it is so far away from here to travel for a day in the mud and not have a car to wash afterward! More info here if you are interested http://www.autocar.co.uk/landroverexperience/
It isn't going to be a cheap day out at £199 either, but you will get a free copy of Land Rover's excellent Offroad Driver Techniques DVD and a huge smile on your face afterward through having had more fun on 4 wheels than you have ever thought possible. A Carbon Footprint is the mark a lump of coal makes when it's dropped on the ground.
