At best is what I am the day before I ship out for parts unknown. Today was no exception. I spent the morning sorting paperwork, reading procedures, emailing back and forth with my oppos on the ship, charging batteries, packing, etc. At 1:45pm I went out and started up PW's SUV in preparation to run errands, pick up LP from school, and take her to a doctor's appointment in town. I haven't driven my pickup truck much, lately, so I started it and let it warm up. It was -5 this morning.
After some last minute running around, PW and I finally left the house and completed the aforementioned errands and appointments. At 4:45, as I drove to the mall for an appointment with my barber, I realized I left the pickup running in the driveway. Shit.
I estimated that I had less than a quarter tank of gas when I started it. It gets probably 10 MPG idling, which must equate to 10 GPH, or Gallons Per Hour. I arrived home expecting the truck to have run out of gas with a dead battery from running the fan I left on defrosting the windshield. It was still running, had over a quarter tank of gas and I never turned on the defroster, at all. The windshield was still frozen solid.
