We have homeschooled in the Kansas City, Mo. area and the eastern Kansas area. Kansas is simpler because we don't have to track hours per subject and location, as I did in Mo. However, as a previous poster mentioned, we are catagorized as "private schools" and there is no homeschool law per se, which I find rather odd. But, since it hasn't caused legal problems for Kansans, we just go with it. Both areas have strong homeschool communities and many opportunities including sports, fine arts competitions, etc.
In my opinion, both would be fairly easy to find some land and have livestock. In fact, in Topeka, you can even have chickens in city limits! I don't know about goats. And, eastern Kansas is green and has lots of trees. It looks pretty much the same as the KCMO area.
