East Contra Costa Historical Society lost a longtime friend and supporter with the passing of Rod Linn. Rod was the definition of community volunteer who was always there with a smile and a helping hand. Whether he was repairing the copier, perking coffee for Opening Day, or creating a festive mood with his music at the BBQ or Christmas on the Farm, Rod was always there. We will miss you, Rod
