~7.9 miles, ~40 minutes. Not too shabby! I took it easy as it was the first trip for this commute, and that bike has only had a 2mi shakedown ride since I rebuilt it and I wasn't confident in my handiwork.
Route taken, the astute Bostonians among you will notice the very stupid turn after crossing the longfellow. I shall never again ask a bike courier for recommended directions on the fly without being very specific as to WHICH waterfront industrial park I was headed towards. I'll take some blame for that one.
