Did you read the text under the map? "Do I really live in Edmond?" All of the area north of Waterloo in that area is Guthrie schools, most of it Guthrie telephone prefixes, 911 calls go to Guthrie central, a majority of it has Guthrie zips, and in fact the Guthrie city limits technically by means of a so-called "Fenceline" (a thirty foot wide strip) borders Waterloo road for several miles.
Due to the lack of I smiley in your original "Guthrie Sucks" post yes I assumed you were not joking....
