I also didn't care about class as I moseyed home and took in awesome Bronx/Upper Manhattan sights. Such as the Croton Aqueduct, which distributed water in order to make the construction of New York City possible in the early 1800s. We also saw the super cool (but unfortunately closed) High Bridge and Highbridge tower. Our fingers are crossed that the tower and bridge will be open to pedestrians soon!
Yes, I am now in (intense) pain. But a weekend well-spent is always worth it.
