The Hudson River Waterfront Trail is fantastic. It is eighteen miles long and thirty feet wide.
The entire time you're on the trail you can see the New York City skyline and watch hundreds of people scooter, run, roller-blade, and stroll! There are great parks and benches interspersed along the way, which is terrific for all, including people like me, who think they can run, but really can't...and for people like me who need a place to eat pastries...
What are the stories behind these sunken sailboats?!
