Mary Lebrecque of Gorham shops in Gammon Landscaping Nursery's new 3,600-square-foot covered shopping area during the grand opening Friday in Auburn. "We've never had a covered shopping area before this, and we actually have parking now," owner Rick Gammon said. He made improvements to the business after a lightning strike destroyed a barn last fall on the Route 4 property. Starting in October and working through the mild winter, the business added a porch, a patio, a pavilion, a pergola and parking.
