Yes, we did it - but just in the Museum of Constitution in Philadelphia! What a great city! Just a little more than two hours drive away and we haven't been there before.
After visiting the main attraction (The Independence Hall, The Liberty Bell and the Museum, of course) we left the old town and just strolled through the city for hours. I loved the small street with the red brick townhouses in the south and all those wonderful street cafe's.
Much more relaxed than NYC.
Most impressive building: Kimmel Center for The Performing Arts. Wow!
And we ("foodies") enjoyed our dinner in an really amazing Cuban restaurant.
Already looking forward to going back! Let's hope it doesn't not take us again six years...
