Princeton lies roughly halfway in between New York City and Philadelphia. While New York is the focus of most of the sightseeing opportunities during the Olympiad, we also will be giving participants an opportunity to visit Philadelphia, where the USA began on July 4, 1776. After leaving Princeton at 8am, participants will have a chance to visit Independence Hall, the Liberty Bell, the National Constitution Center, the Benjamin Franklin Museum and other sites pertaining to Colonial America, Revolutionary America, and the early years of the Republic. After lunch (and a chance to get a famous Philly cheesesteak, of course), students can opt either to return back to Princeton by 2:30pm (2pm on Day 6), or continue spending the afternoon in Philadelphia. Afternoon options include trips to the University of Pennsylvania, and either the Academy of Natural Sciences or the Franklin Institute. The afternoon portions of this tour are not available as a half day option.
