Yah, I was covering both bases, sorry if that wasn't clear. Raven and Pace can let you know about local groups (chances are they know of a number of them or people who could tell you) and yahoo groups is a great place to search. I'm on a Ketchikan homeschool association yahoo group and they announce fun happenings, set up "choirs", field trips, "school" pictures, etc. Log rolling contests, christmas around the world displays, submarine base tours, birdwatching, homeschool book/supply swaps, etc.
Best of luck!
