S.T.
socialization was an issue for the first few months with my older son. we didn't know anyone else and the only groups we could find were very christian, to the point where you had to sign a 'statement of faith' to participate, and of course i could not in good conscience do that.
but once we hooked into the secular homeschooling groups we never, ever lacked for things to do. not only learning co-ops, but field trips, sports, hikes, and lots of just plain hanging out. we had to weed through all the opportunities and make sure we didn't spread ourselves too thinly.
i was on 3 different email lists and participated in 2 co-ops on a weekly or bi-weekly basis. and if there weren't classes in what i wanted my kids to take, i'd teach 'em here. every time i did so (several times a year) my house would be overflowing.
secular groups are small compared to religious groups, but they're out there!
and of course, if you want religious groups, the opportunities are even greater.
don't let that stop you from homeschooling! my kids were with other kids several days per week!
