Back in 1972, we had an early snow storm hit Tonopah, Nevada and it completely iced up the southbound grade going out of town on Hwy.95 - the major North / South route through Nevada. Reports came back into town that there was a major pile-up of trucks on the grade. The towns one tow truck went over the hill, took a look and came back saying "No Way". About two dozen semi's, doubles, & triples jackknifed, on their sides, on top of one another, there was even a set of triples that had completely wrapped the trailers around the tractor - a real MESS.
I put the studs in my mud & snow tires, and put on the tire chains, on my 1967 Toyota Landcruiser and got the tow truck operator and we went over the summit to try to straighten out that mess. I had an 18000 pound PTO winch with 100 feet of 1/2 inch stainless steel aircraft cable on the front of my Landcruiser, and between the tow truck & myself working 15 hours we managed to get most of the vehicles back on the road & in service. I made enough money during those 15 hours to completely pay for my 3 week vacation with money left over.
