Yes, it is great fun!! Not done it as a driver yet as my babies are still growing, but done a few as backstepper. Ours were a drive out in forests or nice tracks, and then back to a coupe of fields for the "tasks". We've had things like driving round a circle marked on the ground with a wheel either side of the line, filling a bowl with water carried by the backstepper cup by cup, mini cones courses, just fun stuff that has a little skill involved but isn't intimidating and seems to usually end up with the backstepper making a fool of themselves (I remember one involved me throwing balls in a bucket and then running round a circle as fast as I could?!!)
Give it a go, in my experience they are very friendly and low pressure, so great for novices, and there may be a degree of friendly "helping" (aka cheating) going on!!
