There's 3 ASDs this year.
One on Friday, one on Saturday, and one on Sunday. I'll be at this one since it works the best with my schedule although I will have to leave Saturday afternoon so I will not have much time to explore the city.
To make good use of your time, after ASD, you should walk east untill you hit columbus circle, then head down broadway.
It'll take you to times square. A little further down you'll hit Macy's
Then, when you get to 34th street, head east, until you hit the empire state building. Go up if you want.
Then walk north along 5th avenue until you hit FAO Schwartz (play with the toys, you know you want to) and the apple store.
Then walk into central park, meander a while, then head back towards columbus circle.
After that, walk up Broadway, until you hit 70th street. Walk into Sabon (soap shop) and wash your hands. (no really)
Then get some hot dogs at gray's Papaya. Then walk up Columbus, about 2-3 blocks, enter Jacques Torres and get some hot chocolate for dessert. Now turn around and walk back down columbus and back to the law school to get back to where you started (if you want)
