http://www.patternliteracy.com.... Toby Hemenway would be the guy for North America. He is located mostly in the Washington/Oregon area though. I think there is another guy in Maine or East/Canada also. When you live a long time though, sometimes people you think are there, are not there anymore (!) Permies.com is a northern oriented forum run by Paul Wheaton.
Warning though, he ran me off for mentioning the word "glyphosate". This group would probably be the closest one to Indiana. I remember one of the participants turned out to live near my old home place in Michigan (near Traverse City).
