I'm never going to be able to convince any of you that this really happened. First... my cul-de-sac is full of snow. The plow came by and pushed the big piles out, but the whole street-surface is snowpack. (In these conditions I will regularly back out of my driveway (which is opposite the cul-de-sac entrance) by zipping into the slick in reverse, cutting the wheel hard, and doing a moving 180.) Second: yesterday there were no cars parked along the curb in the cul-de-sac. Third: You're not going to believe this, but the UPS guy came by yesterday, wheeling into the cul-de-sac at about 20mph. He cut his wheels hard, gunned the engine, and did a three-quarter donut around the edge of the cul-de-sac, powersliding his rear wheels through the one remaining snow-plow-pile. Now facing back out of the cul-de-sac (and still moving at a good clip) he drove away WITHOUT DELIVERING PACKAGES.
