...in the parking lot of my landlord, after paying my rent, parked in THE ONLY DAMN SPOT with black ice in it. I was also on the slightest of downhill slopes, barely perceptable. I put my truck in reverse and tried to back out, and I was stuck. Stuck on black freakin ice, on the edge of a crowned parking lot, stuck. So, to attempt to melt the ice, I floored it in reverse, then tried rocking back and forth, and after about 5 minutes of this, I finally started to move, and eventually back out. WHen my tires hit dry pavement, the truck stalled, adding insult to injury. What a pain in the ass.
