There's no rule but there are a few of us that still believe in common courtesy. Not bogart it at least...It's so childish at him hogging Channel 19 in this manner. I can remember my dad telling me and I cannot recall how many times, when in let's say 1979. Do not talk on Channel 19, Truck Drivers use that for work. Talk on another channel. Little kids were not supposed to being using the CB away. "Talk to your friends on another channel, not Channel 19."
