you know, i toyed with the idea of turning the family farm into something like that, a recreational off-roading place. seemed like there could be alot of issues with it though, insurance, upkeep, ect. would have been cool though, was about 200 acres. sadly its all sold off now, long story short, we got out of farming while we still had good memories of it & before it bankrupt us all, if it could have been a profitable "bussiness" though and id of had the start-up capital.....would have been cool! i dont know of any in central ohio. used to be a yearly mud-run not too far away from me, never went to it, always prefered to play in the snow, mud just gets everywhere you cant wash out & rusts things out. snow will melt & run out on its own. any trail stuff id do would have to be mild enough not to do damage, only got one truck & its my daily driver.
