On January 2, 2013 the WooFDriver and his crew took the PAK on a Mushing Tour of the C&O Canal Towpath in the area of Violettes Lock by mile marker 22.1. Violettes Lock also known as Lock 23 was built in 1830 out of Seneca Red Sandstone in Montgomery County, Maryland. It could take 2 1/2-10 minutes for each boat to get through a lock going either direction on the canal, but the average was 3 minutes per boat.
