Hendie at the Nachtwacht at our visit to the Rijksmuseum in Amsterdam. The painting is called the Nightwatch, not because they were keeping the city save at night (which they probably did as well), but because it used to be a very dark painting. After fixing it up, it became much lighter. Nobody started calling it the Dagwacht (Daywatch) however. My question: what's the Baywatch called at night?
