(Sounds like some bizarre law firm or something... )
Since heim asked the question about volunteering over here, thought I would go ahead and mini-hijack... ST is right about church being a good spot. However, the ole' internets ( ) can provide good info, too. I would suggest just googling a field of interest for you and checking it out in your area....being just outside the Beltway there ought to be just about anything you could be interested in.
OF course, there's also political campaigns getting fired up right about now. Help, especially at the grass-roots level for smaller campaigns, can really make a difference for a candidate you believe in. I'm starting to get involved a little in a very uphill campaign to unseat our 'global warming is a myth' senator (I seem to recall you commenting on this topic earlier!!)
And Puddle, I hope you didn't read any sanctimony in my earlier comments to you, 'cause I question my own feelings and choices weekly, if not daily... I can't remember whether you and H have talked about what your kid-sharing may look like once he moves out; will that be complicated by your homeschooling, or does it actually simplify things by them being with you most of the time?
