Around 1800 Monday, it stopped raining, so I left ExCeL, picked up my luggage from the Ibis hotel, and took the DLR to Bow Church. Even though the CityStay hotel was just west of the DLR station, it took me a few minutes to find it, since the map showed it to the east. Tuesday morning, leaving my bags at the hotel, I got a glimpse of St. Mary's while looking for the tube station, which turned out to be a few blocks west, while the church is to the east. Then I went to South Kensington by way of King's Cross St. Pancras and took the subway (an underground walkway, about 1/2 mile) all the way to the Science Museum. I looked at only 3 exhibits: the history of steam engines, 18th century science and British electronic music. In the afternoon, I returned to Bow Church by the direct route (30 minutes instead of 60), picked up my bags, and took the DLR to London City Airport.
