This was one of the first anglers we happened upon during our trek on the Rails to Trails bike path that runs from Erie to Pittsburgh, Pa. in the Oil Creek State Park, Titusville, Pa. Looks better with black background.
@gardencat - Thank you Joanne! Fly fishermen use a special line that is bigger in diameter and allows it to float. Many of the guys I saw had some pretty bright colored line which makes it stand out more.
