The Arizona Game and Fish Department is increasing their enforcement efforts to ensure compliance with off-highway vehicle(OHV) laws.  In Arizona OHVs are required to have decals but the department reports that less than 25% of OHVs have them.  The annual decals cost $25 and are part of a program that started in January, 2009.  The program covers most ATVs, utility vehicles, dirt bikes and some sand rails and revenues pay for information booklets and riding maps as well as clean up and restoration efforts.  Learn more:  KTAR.com
