This week, I began a mission to photograph all of the nature parks in Arlington, Virginia over a period of a year. The plan, in addition to getting a lot of exercise, is to use the photographs to create merchandise and raise money for the upkeep of the county's parks. I expect to take between 5,000 and 10,000 photographs, as there are over 1,110 acres of parkland in Arlington. Pictured here is a trail in Potomac Overlook Park at sunset.
