Thursday: Arrive in NYC in the morning. Probably MOMA, some cheap kosher takeout, and an evening play (Our Town).
Friday: Rachel will hit the Natural History Museum, and I'll devise something to do that involves games. Neutral Ground is closed; what else is there to do game-related on a Friday morning/afternoon in Manhattan?
Shabbat in Teaneck, NJ with good friends.
Sunday: I say goodbye to Rachel :-( as she will be teaching at JOFA, and I'm basically free until my high school reunion in West Hempstead on Sunday evening.
Monday: I'm free again until around 2:00, then I'm off to the airport.
I'll have no trouble filling up the free time with interesting things to do in NYC - hopefully, I'll also hear from work - but I'm happy to hear from you if you want to meet.
