The National Mall, Washington, D.C.
This is one mall that everyone in the family can agree on. Established in 1965, the http://www.nps.gov/nama/"target="_blank">National Mall & Memorial Parks is home to iconic presidential monuments and war memorials, the world-class museums of the http://www.si.edu/"target="_blank">Smithsonian Institution, and a variety of festivals and political rallies. Take the kids to gape at the larger-than-life http://www.nps.gov/linc/"target="_blank">Lincoln Memorial, see Lindbergh's http://www.nasm.si.edu/imagedetail.cfm?imageID=205"target="_blank">Spirit of St. Louis at the Air & Space Museum or the http://mineralsciences.si.edu/hope.htm"target="_blank">Hope Diamond at the Museum of Natural History, or just pack a picnic lunch and a Frisbee and enjoy people watching. The best part? All admissions here are free of charge.
