MAPPING RELIGION IN AMERICA

I just discovered a very interesting set of maps showing religious affiliation in the continental 48 states at the "Regions of the Mind" blog. http://regionsofmind.blog-city.com/mapping_religion_in_america.htm I am not sure there is anything one probably cannot already assume, except I was surprised at the low number of relgious affiliations in the Southeast US which is considered part of the Bible Belt.
