"Automobile drivers aren’t skilled enough to note that when the big trucks sort themselves more easily (a result of this on-air activity) that traffic moves much more easily. GPS won’t do this by itself." Geez Ain't that the truth. More than a few times in the big truck on the big roads, there would be a stoppage somewhere up ahead. Because we were ALL on CH19, even with skip rolling in, someone up ahead would notify to all what lane to avoid, what was going on, etc. I actually remember a time hauling equipment into PA (I-81 south) when all lanes ahead were just brake lights. It was a long stretch before the next exit....creeping along in a low gear on that 10speed is not as much fun as you think! the chatter on CH19 was about an accident actually in the center grassy median at least a couple miles ahead. One driver familiar with the area gave really good advice, get off the next exit, follow signs thru that town, stay on the truck-route, after about 20 miles you can get back on again. I tell you what, it was good advice, and when you're in a "convoy" of other big trucks on the same unfamiliar route, having CH19 is a must. On the accident: once we got up ahead enough on the big road.....there was a Freightliner Cascadia all busted up in grass, with a camper trailer rolled over near-by. More than a few witnesses saw the brain-dead camper driver change lanes right into the path of the Cascadia.....nowhere to go but into the grass. I was in a hotel later that night watching the news, apparently the truck driver was pretty banged up, but all survived. I say all of this because "CB stories" are not just about radio-alone. We're out there making a living, but also trying to stay alive. Skip conditions never were a problem, even back in the "old days" with basic 4w radios.
