William P. Niedringhaus was the first to envision the Fairfax Cross County Trail (www.fairfaxcounty.gov/parks/cct/). He led several Cross-County Hikes from Lorton to Great Falls in 1998-2001 to promote the idea. The trail officially opened in 2007. Bill won an Elie Doyle award in 2001 for Cross-County Trail advocacy and shared one in 2007 with five others (including PHTA board member Robin Rentsch). He is currently president of the PHTA and Fairfax Trails and Streams. Bill designs, builds and maintains many miles of trails.
