For all you petrol heads out there, here's your chance to take to the wheel in a way that anywhere else would be downright illegal! Have some fun ripping up the countryside in your choice of machine, from Land Rovers through to 3-ton trucks. Some places will let you challenge your own 4x4 if you're crazy enough. With full instruction (and safety training, of course) this is a chance for some really wild motor activity. We think the muddier the better, so this is a great winter activity idea.
