On Wednesday, August 12, volunteers will gather at Gallagher Hill Open Space to restore the 11-acre natural area on Mercer Island's northeast corner. If you're into native plants and don't mind getting your hands dirty for a few hours, it's a straightforward way to help maintain the trails and stream ravine that make this spot worth visiting in the first place.
