Swimming Holes: swimming_004

Cody Yeagle, center left, and Mike Bretado, center right, walk towards the Henryton Tunnel while leaving a swimming hole in the Patapsco River in Carroll County, MD on Monday July 16, 2012. Swimmers walk through the tunnel to get from one well known swimming hole to another. The tunnel was constructed in the mid-1800's by the Baltimore and Ohio Railroad. It has gone through some changes since then, including being rebuilt in 1903. It is still in use today. (Photo by Matt McClain for The Washington Post)
