We'll meet at the brand-spankin'-new playground at Roberts Park. It's on Skyline Blvd, about a half mile North of where Joaquin Miller Road hits Skyline. Pay the friendly parking machine,$5.00 in ones, a five, or quarters, at the kiosk, then look for the playground on the left, up the hill just above the pool (which doesn't open until 3:30 on that day).
