Heading for New York, what to do?

[A-Polly]

In addition to the great suggestions you've gotten already, would you enjoy some outdoor theater? NYC has lots of venues in addition to Central Park. In keeping with Tips & Deals theme, these are usually free (although donations will be requested, of course!). At the Soldiers' and Sailors' Monument in Riverside Park, you sit on the steps while the actors perform in front of you, in the open, under the stars (unless there is a rainstorm!).

I've not been to this park, but looks like there is an actual amphitheater, with seats and all. And the play looks cool!
