Here in Nebraska, CB never went out of fashion with the local short-haul trucking community. All of the local guys still use channel 19, and we now have an expanding population of immigrant truck drivers in the area using channel 22 in Spanish. I live 5 blocks away from a grain elevator, and 4 miles from a feed distribution site, so I hear a lot of CB traffic every hour. The elevator uses either channel 19, or sometimes channel 12 to instruct drivers how to back around to the loading/unloading areas etc. I live in the middle of nowhere, so the only thing I ever hear on GMRS is my own family, and some occasional ducting from a grandfathered business-licensed system on .625 that is used by a concrete company east of me about 70 miles. (They have a phone patch. Not sure that's legal even on a grandfathered system.) On FRS channel 1, I quite often hear the little girls across the street playing with their walkie talkies, but that's about it.
