Among the many things they don’t tell you about becoming a parent is that your life will once again revolve around the school year. Apparently our Summer vacations are the result, not some anachronistic agrarian calendar, but of an effort by late 19th century school reformers to standardize academic schedules between rural and urban areas. In the days before air conditioning, it simply made sense to take a break during the sweltering months of Summer. That same logic applies to life in Washington DC. No one moves here for the weather, and, as its denizens are fond of recounting, the city was built on a swamp. It is beautiful here for six weeks in the Spring and six weeks in the Fall, but at all other times DC weather is something to be avoided, and that goes double for the Summer months. Congress leaves on recess for much of the Summer, so it makes sense for much of the lobbyists, the nonprofit activists, the think tankers, the policy wonks, and the journalists to leave as well.
