Travel advice: Boston, NYC

Hi everyone,

I have some business to do in Boston by the end of February. I plan to add a couple days of vacations (2/26-3/8 to be precise) and now looking for some ideas.

So far, I've booked a hotel from Sunday to Friday in the city center in Boston. On the following weekend I might rent a car and see some places. I thought, it would be nice to spend then remaining days in NYC.

If I make it to NYC it would be nice to see the Magnum contact sheets exhibition. Has anybody seen it yet? I recon, it's a better idea to go to NYC by bus instead of driving there.
