Volunteers will be celebrating Earth Day (Thursday, April 22), by clearing out invasive plants at Lower Kinnear Park this Saturday, April 24. For those interested in participating, volunteers will be meeting at the Roy Street entrance to the park and working from 9:30 a.m. to 12 p.m. The clean-up is being spearheaded by the Scientology Environmental Task Force, which has been an active supporter of community group FOLKpark‘s efforts to redevelop and revive Lower Kinnear Park.
