So the kids are finally of that age where a trip to our nation's capital will leave a lasting impression. So besides the crowd for the city's Independence day celebration. We're looking forward to seeing the national parade. As well as the White house, Capital building, Smithsonian (American History; Air and Space), Pentagon's 9/11 memorial, Arlington cemetery, and the Bureau of Printing and Engraving. So what else is there to see or do that might not be the most popular destination?
