Cloudy skies and the threat of rain couldn't keep more than 4,500 volunteers from turning out statewide Saturday to remove trash and improve watersheds as part of the SOLV Beach & Riverside Cleanup.  Volunteers removed an estimated 67,900 pounds of trash, and cleared 12.5 acres of invasive plants. Cleanups were at 125 sites in Oregon and SW Washington.  Cigarette butts were again the most common item picked up across the state. 8 projects will take place next weekend as part of National Public Lands Day.
