Last time we were in London, you entered the British Museum via its vast courtyard and staircase spilling onto the sidewalk. This time we visited the day after ISIS murdered 23 people at a pop concert in Manchester, England, attended mostly by teenaged girls. On this day, black iron gates blocked the courtyard from the sidewalk and we were permitted entry only through a carefully-guarded little gate and then a bag check under a tent some distance from the grand building. When I had awoken that morning, Todd said, "We're not in danger, but I have to tell you something," and then we listened to the BBC and tried to make some sense of what it meant to London, to Manchester, to us as tourists, and of the nature of this danger pervading our world. The government said another attack was "imminent". We observed plaques and banners memorializing other English terrorist attacks as we walked around the city, including one thanking emergency workers in the Westminster attack earlier this year. Two days after we got home, we listened to the BBC as the London Bridge terrorist attack unfolded. These photos aren't about that. They're a few impressions from our visits to London's great museums. A terrorist attack was imminent and we went to museums. People went to work and rode the subway and relaxed in parks. Still trying to make sense of it.
