New York In July?

I just received a pre-invitation to the 50th anniversary gala for the Public Theater in NYC. It is likely to be a star-studded event. The only problem is that it is on a weekday, a Tuesday night in July, which leaves me with a child care dilemma, since my husband would be working. I think it would be very exciting to go, so I'm keeping my options open. I was last in New York in August of 2001, just before the horrible events of Sept. 11th took place. I've been meaning to get back ever since, but there's always something that makes me call off my plans. I guess I will have to just wait and see. I certainly miss the Big Apple, it is one of my favorite places to visit.
