Mike. Way back in the days before GPS system, I was a expedite freight owner operator with a company based in Toronto. Almost 90 percent of my loads had US destinations, all over the lower 48 States. I had the standard Rand Mc Nally trucker's atlas in the cab, but every time I entered a State that I had not been in before, I stopped and bought a State map. Same thing for new cities or towns I was delivering to. It wasn't long before I bought an accordian file holder with 26 spaces for all of the letters of the alphabet, which I filed the maps in.
I could navigate from any starting point in Canada, to any destination point in the USA, using the maps I had on board. Because my vehicle was not an 18 wheeler ( it was a Ford E 350 cargo van ) I didn't have to stop at scales ( weighed under 10,000 pounds gross ) or keep a log book, I could drive for 16 or 18 hours, stop for fuel ( double gas tanks under the van ) sleep for 6 hours, then get going again. Paid by the mile, 70 percent of the invoice that our company charged the customer. I did that for about 5 years. driving about 120,000 miles a year.
By the time I quit the job, I had over 400 maps . I gave all of them to a new guy who was just starting with the company. A few years later the first Qualcom sat system ball antennas started to be seen on the roofs of truck cabs. I still have the southern Ontario street atlas in my car, for looking up streets in towns that I don't go to very often. JIM.
