The event was first held in 1762 and each year, more than 150,000 people participate in the parade and nearly 3 million people line the city streets to watch the demonstration. The U.S. Air Force Honor Guard was featured in the parade, which was part of their U.S. northeastern outreach tour. (U.S. Air Force photo by Airman 1st Class Valentina Viglianco)
