Welcome to the 18th Century
When I visited in the winter there were costumed interpreters in the house, and you really got a feeling that this was George & Martha's HOME.. their dining room, their bedroom, the views out the windows are pretty much unchanged. I'm pleased that they were able to keep so much of the property intact, so the present day does not intrude. Yes there are long walks around the grounds and down to the tomb and it really feels like you are transported back in time.
The admission was $8 when I was there and there was a nice lunch room with premade boxed salads and sandwiches that were fresh and good.
