Excited about traveling!

Ken and I are excitedly planning a trip to Washington DC as well as a day and night in Philadelphia and a drive to see the coast (in New Jersey) and over the Delaware and Chesapeake Bays. We have never been that way before and needless to say we are very excited.

We really love history and politics so these places are right up our alley! I have found a few spots that I have found very helpful in planning our trip they are:

• Very helpful and detailed for planning our time in Philadelphia!
• A list of 100 free or nearly free things (with lots of links) to do in Washington DC.
• Frugal things to do in Washington DC.

Do you have any suggestions of things that we shouldn't miss seeing while we are there? I would love to hear your input!
