Well, today I found out. Had to go to town for tractor fuel, and Jack thought he would meet me at the corner but I just kept going to the lane way, stopped briefly to change range, dropped the bucket and started pushing snow. Poor Fat Jack was just appalled a the treatment and chased that tractor for another 200 yards or more. The answer is just over 2/10 of a mile. I have never seen anything so mad for a ride!!!
