I have a neighbor plow it with a tractor even though that means they have to run my garden over to turn the tractor around. I figure most things can take an occasional running over when they are dormant.
Around here -- and likely where you live -- the frost line runs about three feet deep. So that tractor is running over deeply-frozen ground. It's not causing any harm at all.
And ... 700 feet -- with a shovel?
Success is to be measured not so much by the position that one has reached in life as by the obstacles which he has overcome. - Booker T. Washington
