The requirements for having the best fun ever are simple.
A good fall of snow, a hill and something you can sit on to slide downhill.
It’s the easiest and cheapest way to enjoy yourself, it’s sledding, and now is the perfect time to be doing it in NYC.
There’s one refinement which is putting snow board or automobile wax on the bottom of your plastic sled to increase it’s speed.
Otherwise just point and slide. it’s insanely good fun as you can see by watching the video.
There are good sledding places in all 5 Boroughs of NYC. Go to Gothamist List of Where to Sled In NYC LIKE all ways of having great fun in NYC.
