My morning walk took me past MIT where I paused for perfunctory photographs. It was rather cold so I was happy for the brief indoor respite. Only the early morning hour affords an opportunity to capture these scenes absent the multitudes of students and visitors normally present.  I completed my 4.5-mile stroll in 75 minutes. Normally this would carve out a rather large portion of the workday. Not so when you leave home at 6:30 am and return at 9:30 pm.
