But wait, there’s more….This reminds me of my first trip to Boston as a non-child. It was with my friend Karl to see his cousin Mark. Mark lived in an area of Somerville that I eventually got to know quite well myself (student ghetto) years later. This was about the time the city was changing most two way streets over to one way streets in order to relieve congestion. (Somerville was, and may still be, the most densely populated city on the Planet Earth without exception, believe it or not.)Anyway, to get to Mark’s house, you went down one one-way street and turned left onto another one-way. Sounds easy, right? But there was a sign on that turn that said “No left turn 4-6:00 PM” So in the late afternoon, no going home if you are Mark.
