What To Do In New York, Atlanta, and St. Louis?

Hi all, it’s right on top of us now.  Next week I’ll fly to New York, Atlanta, and St. Louis for the first leg of the book tour.  I know I’ll be busy in NYC, and I already know some of the things I want to see there, but I’d love to have some suggestions about what you think is a Must See.

And I know almost nothing about Atlanta (except for Tom Wolfe and A Man In Full), or St. Louis, short of the arch and people saying, “Don’t get shot while you’re there.”

How about it? Any recommends?
