(Nov. 3, 2011) -- Crossing the Rappahannock and Rapidan rivers today is easy; just drive over one of many bridges. But 150 years ago, river fords were the preferred, and in some spots, only places to cross. Steven L. Walker, owner of Rappahannock River Campground in Richardsville, has chronicled the historic crossings in his self-published book, reports Fredericksburg.com.
