Extension cord of a market sales man. Bright orange. How could I miss it.
Anyone who makes the obligatory comment about "women drivers" gets a lifetime of abstinence.
About 15 years ago I pulled out from the driveway without turning on the windshield wipers (dewy morning and we only live 1 house from the corner with a stop sign where I usually put on the wipers while waiting for traffic to clear. Yeah, careless, I know.) Anyway I proceeded to run into the back of the move-a-house-sized U-Haul trailer that had been parked there for a week. Which I knew about, but was just too distracted to remember. No damage to it, but the car was much worse for wear. Thankfully I wasn't going too fast.
