(VA) (Arlington Regional Master Naturalists) Do you like working outside? Join community volunteers in protecting the local environment from non-native invasive plants and replacing them with native plants.  This is a continuing project typically held every Saturday to reclaim Potomac Overlook Regional Park from non-native invasive plants. Be sure to come dressed for work, wear long pants, long sleeves, and perhaps a hat.  You may also want to bring along your own water bottle, but bottled water and snacks will be provided. Ages 9 to Adult.
