I just called Nat to go out and have brunch at Henrietta's Table in Harvard Square and a panting Nat informed me that he was biking to Provincetown and back. Unlike his last trip two weeks ago he left Boston fairly late. I just got the following SMS with Nat's current location:
14:50: N:41.690170, W:-70.317350. 74.9 miles from home or about 100 minutes by car.
18:21: Nat has arrived to Provincetown. The trip is one hour shorter than his last trip. Now the painful return home begins.
