If you only have one day to see DC and you have kids I highly recommend you do it on bikes. We were able to see so many places and it would not have been possible without the bikes.
It was the first city I wish we had more time to explore but we had three goals in Philadelphia, see Independence Hall, The Franklin Museum and leave with enough time to get to Washington, DC and continue driving south toward Auburn, AL. We accomplished all of those things, saw the Liberty Bell and the kids earned another Junior Ranger Badge.
Boston, the heart of a revolution. When planning our trip, this was one of the important stops we wanted to make. Walking the freedom trail was an experience we wanted to allow our children to have in order to understand the importance of our country's independence.
The name Ohiopyle is from a native american indian word "ohiopehhla" meaning white frothy water. We were drawn here by Falling Water but the area has so much more to offer.
