When Wayne Allard saw the new U.S. Forest Service guidebook for managing off-highway vehicle trails, he was astounded. As the American Motorcyclist Association’s lobbyist, he seethed over its derogatory and unfitting remarks, like “Managing trails for OHVs (off-highway vehicles) can be a lot like herding dragons.” And as a former U.S. senator from Colorado, he saw political danger in the report’s lame OHV humor — “They’re big, they can cause a lot of damage, and they sure can heat things up.”

The 316-page document with the unwieldy title — “A Comprehensive Framework for Off-Highway Vehicle Trail Management” — concluded with a similarly flip comment by author Kevin G. Meyer, a National Park Service trail specialist: this document, he wrote, had been developed “to help trail managers corral the OHV management dragon,” and “to help keep the beast at bay. Happy herding and happy trails!”
