From high above the NYC skyline, we head north - beyond Manhattan's Upper West side and the George Washington Bridge - tracing an historic route inland. Here, we soar above the contours of the Hudson River and picturesque river towns like Poughkeepsie - exploring iconic symbols of America, like the West Point Military Academy and Newburgh's Motorcyclepedia museum. Along the way, we also reveal the rugged beauty of the New York State interior - from Bear Mountain State Park to the Hudson highlands. We finish our journey at the town of Rhinebeck, and its world-famous aerodrome.
