As a Ark-La-Tex log-hauler, I get "DoT'd" (inspected) about monthly by DPS in the Tahoe units. They have portable scales, but I've never seen an actual CB in them. They have you sit in the passenger side while they check your paperwork and hopefully print you a "NO VIOLATIONS DETECTED" receipt, which my company pays driver a $50 safety bonus for obtaining. I chatted with a Trooper just last week, who said that when he goes to do border-patrol duty, he chats with a trooper friend stationed in El Paso over the system down there...he got told to quit tying up every repeater on the system even tho it was like 2am...lol. He said that 3 gangs exchange full auto weapons fire directly across the Rio Grande each night. I guess a question would be, can their radios have a CB frequency (channel 19) programmed in?
