some people enjoy it there. i don't, i only live about 15 miles from it.
basically tom's been banned from keeping animals so has turned his farm over to bikes and 4x4's for £7.5 a day for bikes.
what you'll find are lots of hills, lots of well worn tracks leading in every direction and lots of big ruts. as a result there are bikes and 4x4's going in every direction so beware on a busy day!
there are no facilities nearby so if you go make sure you take every thing you need.
finally when not riding make sure your bikes locked up. there have been several bikes stolen from there and it is a favourite spot for people from out of the area to come and ride stolen bikes. the local police do stops on people attending the farm regular and have recovered stolen bikes.
obviously the above is only my opinion so have a look around other sites, but as i said i struggle to find anything good to say about it, thought tommy himself seems a tidy enough chap.
