Broke down at about 1800, with 28 stops left. Called it in, got lock box combo no spare keys in box. Battery dead. Mechanic asks if I have been using my flashers all day. I told him of course I have, I'm blocking almost every street I'm delivering on because of the 3 foot snow piles on each side of the road. Tells me that I can't use the flashers all day in the newer Workhorse trucks because it kills the battery. Screw that. If my truck got hit while parked, first thing they would ask was "why didn't you have your 4 way hazards on?"
