Sorry, I'm in PA. Most people connect via yahoo groups around here... Have you tried searching for ones in your area? There is this Western Region Unschoolers group: http://groups.yahoo.com/group/WesternRegionUnschoolers/
And this Montana specific homeschool group:
Some people meet at La Leche League meetings or something and then go on to homeschool. So you can try the reverse, too. Look for crunchy groups and then see if anyone in them are homeschooling rather than seeking out homeschoolers directly. And you might make some non homeschooling friends that way, too. I've found common parenting styles to be much more important than being homeschoolers. Around here the older homeschoolers are just as busy and unavailable during the day, anyway.
