You could probably homestead in Round Rock area. I think all the counties have different regulations. I know of some families that do raise animals and stuff in Round Rock.
I'm living in North Austin and homeschooling is going to be great. No reporting to anyone or anything. I'm excited and hope it stays this way. I don't have plans on getting involved with homeschool groups personally, but if you like that, there are plenty.
