We went on a University of Delaware Academy of Lifelong Learning bus trip to Washington, D.C.
We started in the National Gallery of Art, then walked to the front of the White House. We arrived just after the area was cleared of people. The Secret Service police won't say what is happening or how long the situation will last, so we walked around the Ellipse (it was also fenced off) to the Washington Monument, then to the National Museum of Natural History.
The cherry trees had buds but no blossoms.
