Historic White's Ferry is the last of 100 ferries that used to operate on the Potomac River. This ferry, named after the confederate Civil War General Jubal A. Early, connects Whites Ferry Road in Montgomery County, Maryland with a road by the same name in Loudoun County, Virginia. The cars line up on what looks like a boat ramp and drive down onto the ferry. Once loaded, the ferry follows a wire cable to the other side of the Potomac.
