The traffic jams on Fifth Avenue are no joke during rush hours. It's time to escape the madness. Set sail on the Hudson River where there's zero traffic. The Downtown Boathouse is an all-volunteer organization that provides free access to the harbor in New York City. You can take one of their short classes (held Wednesdays) or, if you're feeling confident, grab a kayak and life jacket (both provided) and head out on the Hudson.
