I'm having a potluck on Saturday the 30th. I know it's not the right week or the right day, but that's when it seems to work for the most people that I've talked to. I'm out in the burbs, in Wallingford near the train station. It should good time to get out of the city and enjoy (slightly) cooler weather. I'll have the grill going and a slip and slide (I'm hoping to track down a Super Crocodile Mile). We also have a badminton set and a couple of lawn sprinklers. You can come by car, train, trolley, or bus anytime from about 5:00 on. Let me know if you're coming by anything other than a car and I'll give you walking directions or make sure you have a ride from the station.
