I'm wondering if anyone has suggestions of what to see/do in this area in late April? We are interested in history, outdoors activities.

Our plan at the moment is to hire a car in Washington DC and visit Gettesburg and Lancaster (my husband's family homestead has been turned into a museum, so it really is a must see for us) before returning to DC.

We have three days (two nights) to fill, so I thought we should be able to fit some other things in, but I am struggling a bit to figure out how far is reasonable to drive and what we could get to in that time.

An american suggested we do some of the Skyline Drive. I have been told by other Kiwis that it is a bit underwelming if you have been to the South Island of NZ, but I thought they might be being excessively parochial - is it worth doing?

TIA
