Bruce,
Traffic on I-95 from north of Richmond through DC and Baltimore will be miserable Bruce. Leave early. I live 1.5 miles from I-95 just north of Quantico MCB and will leave at 0700 to get there by noon!
Take the shortcut through central VA; I-64 east to Zion's Crossing, north on US 15 through Gordonsville and Orange, then State 20 to Wilderness to State 3 to Fredericksburg and north on I-95. Beautiful country and you go past the Wilderness and Chancelorsville battlefields.
