I went to take pictures of any marks in my driveway, can't find any to speak of, never mind any that would show up in a picture. My driveway is rough enough so any marks made by the V-bar's on the chains don't show up. I saw them last spring when I made them, but I can't find them now. I do have some marks where I ran into an snow bank and stopped, but the tractor kept driving after I took my foot of the HST go pedal and it spun the wheels on the driveway. I took pics of that... but I left my camera at home and I am now out of town on business.
