Bring your truckloads of pine needles between 9 and 11 a.m. Saturday to help build the ground cover at the Dogs Run Free off-leash dog park in Condon Park, Grass Valley. Yellow-shirted volunteers will direct trucks and trailers through the service gates and help unload. A couple acres need to spread, so volunteers are encouraged. Bring dogs, pitchforks, shovels, wheelbarrows and work gloves and enjoy a lovely fall morning at the dog park. For information, visit http://dogsrunfree.net.
