Volunteer Isabelo Chio maneuvers his wheelbarrow while on his way to get another load of compost as he works in the garden Thursday morning at the Fort Vancouver National Historic Site. Chio said gardeners had just harvested squash, and he was adding compost to prepare the area for future planting. Chio has worked as a volunteer at the garden for six months. “I like to learn and I like to use my hands,” he said.
