With free concerts taking over the city this weekend (Bon Jovi at Central Park, the Breeders at McCarren Pool, the saw lady in the Union Square subway stop, etc.), open house turnouts may take a hit in the face of all that culture. Or not. You can't keep a dedicated home-shopper away, so let's open a thread for a discussion of open house visits. If you're out and about in the New York City real estate market this weekend, let us know what you're seeing out there: crowd sizes, market conditions, great or gruesome finds, and of course, reports on any brokers offering IMAX tickets to the Dark Knight next weekend. Your thoughts in the comments, if you please.
