Yesterday we saw the Natural Bridge (picture group 1) and then we went by an old mill (picture group 2). We then drove through the Shenandoah National Park. We went to the Greenbelt Park campground near Washimgton D.C.at which point it was too late to write the blog.
Today we went to Washington D.C. by subway and walked near the White House. Although I was melting from the heat we managed to get photos of the White House and the Washington Monument (picture group 3). After this we went to the Smithsonian Museum of American History (picture group 4-6) where we ate and then looked at exhibits on inventions of technology and other things. We had dinner at a restaurant and then returned to camp where we took pictures of the fireflies (group 7, taken with I phone app slow shutter cam).
