I saw that...I lost a water pump once out in the middle of nowhere in the freezing cold in north central Nevada one time. Six hours later a County Sheriff drove by and took me in to Eureka Nevada. I keep a thick blanket and insulated coverall on hand. I just got all tucked in and was hoping to God someone would come by. That candle idea may have warmed me up some that afternoon. Good thing I didn't have to spend the night out there. These days I call it quits before it gets to late out on the road. When I was younger I'd dive through the night and stop for a snooze at rest stops and all, but that job I covered All Colorado, New Mexico, Utah, Nevada, and parts of Wyoming, West Nebraska and West Texas. I'd drive 60k plus every year in a Chevy Lumina. I also keep fire stater sticks and cheap poncho's that I've given out to folks I see walking in the pouring rain and for myself.
