There is an extended family trip to the Vineyard going on that week, I am not sure exactly what days, but that's easy to enough to get to that I can go on my own and catch up with them. I'd really enjoy seeing everyone and can probably fit to any schedule. Mike's place would be really good for a crowd. Perhaps people can speak up if they will be in-town at a Siggraph hotel without a car, and we can see if there are enough cars for rides. Mike, is commuter rail an option? We could easily pick people up at some station near your house.
