I found out a good way to describe how long my commute is: about three minutes more than the length of the second movement of Beethoven’s 9th (the greatest movement!)
On the other hand, that measure proved inaccurate the very next day, when I also found out the answer to “is the drawbridge on Lake Shore Drive ever used?”
(channelling my inner Stanley Kubrick with a little well-timed help from 98.7WFMT). The whole opening/closing of the bridge did cause quite some delay, but the process did, in in the end, finish.
