Sunshine and temperatures in the upper forties lead to much snow melting on Friday. Above is the worst section of our driveway. It never receives any sunshine. With a little weight in the rear of the bed of our little pickup truck, I'm pretty sure we could make a trip out, but since we have no where we need to go, we didn't try.
With the low angle of winter's sun, even a slight change in the road's tilt or direction can make a big difference in whether or not it receives sunshine and melts the snow. Above is the beginning of the section shown in the top photo.
