Just came back from riding a pretty popular trail at Ohiopyle (30 miles or so). I was at a pretty good clip going maybe 30 MPH, so I was passing alot of people. During this hour ride, I passed no less than 40 families. I couldn't help but notice that almost none of the kids in these families were wearing helmets...in PA, anyone under 13 MUST wear a helmet. Next time I ride this trail, should I stop and let the families know of this law?
