I got an E-Mail today from the DNR saying they're holding a sound measurement class this Saturday at Straddleline ORV Park. Chris Real is a rider and does a lot of work for the motorcycle industry. I'd recommend anyone who can, take this class. The Washington State Department of Natural Resources (DNR) is offering a free training on how to measure sound levels from off-road vehicles from 9 a.m. to 1:30 p.m., Saturday, April 18 at Straddleline ORV Park, 15015 State Route 8 West, McCleary.
