There is a difference in coverage: Search for "ash"

in the three Google Custom searches that I created today and it shows clear differences (as you would expect) in coverage in the 3 grand divisions. Of course as time elapses the count will change but as of now:

East TN Newspaper search for "ash" lists 79 articles

Middle TN Newspaper search for "ash" lists 47 articles.

West TN Newspaper search for "ash" lists 17 articles.
