Here's a clever idea we spotted at the Medlock Ames Winery in Healdsburg, CA: a picnic table as wine tasting bar.
Nelson Byrd Woltz Landscape Architects (responsible for the outdoor area) started with a wooden picnic table, then replaced the middle slat with a gutter. The result? A table cum wine cooler, perfect for accommodating the winery's guests.
