We enjoyed our time in London this morning. We rode the Underground (their subway system) to City Doc, the travel clinic where we got our Yellow Fever vaccines, and then walked back a few blocks and visited Buckingham Palace. We strolled around Picadilly, window shopping and ot a little London bus model for our grandson. A delightful time. We made it back to the airport where we had stored our bags just in time for the rain to start. We're all set for our next leg of flying tonight at 9pm into Addis Ababa.
