For you statistic lovers, here's the plot from my GPS as created by EveryTrail.
-- 5-1/2 hours out, 5-1/2 hours back. 8-1/2 hours in the air.
-- 41 mph average speed including stops.
-- 50mph typical airspeed.
-- Maximum altitude was 5,000 feet to cross the Chesapeake.
-- 433 total miles.
-- 17 gallons of gas (my tank is 14, so I refueled once).

I like to stop every hour to change the maps in my kneeboard and pee. Every stop added about half an hour to the flight.
