Oh- if you're in the area and interested in George Washington- his boyhood home at Fredericksburg (Ferry Farm) is also an attraction. It's about a 35-40 minute drive south of DC.

I had to laugh when I was standing on the bluffs at Mt Vernon and recalled the oft-told tale of 'Washington throwing a silver dollar across the Potomac'. The river is about a mile wide there. It was probably actually a piece of slate across the Rappahannock at Ferry Farm- and that isn't easy, either.

Thanks for the story and those links for folks to view!
Thanks for bumping by as they say around here...
I've just spent several very enjoyable hours jumping off from the first link you provided, reveling in the history of George Washington, his homes, his life, early America, etc. What a ride.
Thank you very much.
