Yep, the ole CB lives on in the cabs of thousands of working drivers on America's highways.
Even though it is often disparaged as the trash bin of frequencies, the 11 meter CB band is used innumerable times everyday by professional truckers as an aid to their productive activities. They do this despite the impediments caused by sociopaths who pollute the airwaves to satisfy their boredom and hatred caused by their own shortcomings and failures.
It's encouraging that some law enforcement folks still tune in to help when they can and get it when needed. Even though truckers often are viewed as being anti-police characters who live to violate rules of the road, they actually are some of the most straight-laced, patriotic folks around who are willing to help those in need, and that includes a willingness to help law enforcement as the opportunity arises. In a disintegrating and divided society, they are needed by us more than ever.
