I am heading down to New Haven four days a week this month for a 1 p.m. class. On Tuesday I got caught in a traffic jam because part of Interstate 91 was closed due to some sort of accident. This meant I had to negotiate the back streets--which were congested with other people trying to do the same--to get to Yale. Then I had to deal with the always problematic situation of parking near York and Broadway. I was ten minutes late for class, and I absolutely hate being tardy for something like this. So today, and for the foreseeable future, I am leaving myself extra travel time in case of unforeseen difficulties like this.
