I'd heard about this before, but I finally saw it today while on business in Staten Island.
My trip took me onto a road called Travis Avenue, where a well-paved bike path skirted the road, then crossed over at a couple of points. This greenway looks like it may have several offshoots.
Can anybody bring me up to speed on this? How many miles? What are some good start and end points? Is it worth a trip in from eastern Nassau County to ride with my wife, who is a very casual cyclist?
