Roads are a sheet of ice in Middletown. Back roads especially bad. I went 2/3 of the way up a nice hill, did a slide and spin and returned down the way I'd come. Haven't done that since I lived in Michigan
Nothing official.....just my driveway and choosing the best location to measure from. The sleet has quite obviously packed in the toral measurement as I didn't get one in before it started. So you most certainly have the more accurate measurements.
