Coldest temps. i've ever been in was -26 in Ohio in the 80's. I had to load at Armco in Middletown on a Sunday night. Parked right under the big heating duct when I got in to load, I was the only truck in there. And like you saw, from there back to Lynchburg there were trucks on the shoulder all along the way, with gelled fuel. I was the only truck that H.H.Moore had that was still running. I had enough fuel treatment in the tanks to treat like 4,000 gallons of fuel- seriously, almost as much conditioner as fuel.
Then when I got home I found every pipe under the house was frozen. The kids had opened the door going into the crawl space, playing, and left it open. All the pipes were copper too, and they split where it froze. I'd cut out a bad spot, solder in a new piece of tubing, turn the water on, and there would be another leak somewhere else.
Still chilly here, supposed to warm up tomorrow though.
