I think I just got scolded by 4x4dad ! I respect your opinion, but beg to differ. There are plenty of state and private trails with creek crossings and I don't think the impact of OHV crossing creeks is anything compared to small boat engines that leave 2 stroke slicks on our state waterways. If there is a bridge crossing and we're asked not to ride the creek (Rock Run for example) then we respectfully oblige.
But man is a lot funner going through rather than over!
