There are three pieces of legislation (2 federal and 1 state) that will be of benefit to OHV recreation. Two of the bills have passed their first hurdle - they have received a committee hearing and been reported out favorable. There are still a number of obstacles that could derail these bills.
For a little review, a bill becomes law when it is reviewed and passed by the House and Senate and sent to the president for signature (or veto). For example, look at H.R. 1676, To designate the Johnson Valley National Off-Highway Vehicle Recreation Area.
