Based on the number of coal license plates here in KY, yes, they sure do sniff lines of coal.

One almost never sees any of the other 11 black license plates. I do expect that to change as the new (black) firefighter license plates replace the old red ones.

Lol, but really coal power plants are more dangerous work environments, coal mining as well, and then of course there's the pollution (which, opposed to nuclear, isn't bottled up and stored, and instead just exhausted).
