I don't homeschool but know people who do around here. I would recommend scoping about the homeschooling scene in your area. I think the ease of socialization depends on where you live. Where I'm at there's so many homeschoolers and I think it wouldn't be that tough to socialize but I can see in other areas it would be.

See if there's any yahoo groups or other organizations that can lead you to local homeschoolers. Perhaps if you get to know them a bit now it would ease everyones minds about next year.
