There were many places we did not get to see as we only had a finite amount of time in Washington before we had to drive to New York. One place we saw at a distance everytime we took a cab was the Jefferson Memorial which was located on the other side of the Potomac. This was as close as we got to the monument, although we did try driving there later, only to make a wrong turn and end up heading back toward the hotel (and NY so we kept on driving). The driving is not easy in Washington DC and we did not take the car out of the parking garage until we left for NY. Our apologies to Thomas Jefferson but we tried.
