America has one too many feet, so the federal government is about to lop one of them off with the help of a surveyor from Tucson.
Michael Dennis, who lives in Vail, is leading an effort by the National Geodetic Survey to eliminate an obscure, decades-old unit of measurement known as the U.S. survey foot.
Favored by American surveyors and almost no one else, the survey foot is ever so slightly longer than the more common international foot.
