Come to think about it; I haven't heard the Steele or Caruthersville scale stations in ages.
Yep, it's been so long that I don't even remember the designators they used!
I could pickup the scales near St. Louis on I-55, I-70 near the intersection of I-64 and I-70 and a scale out in St. Clair on I-44.
They used ID's like ''C4 West or C4 East" from what I recall.
The letter and number were different of course for each station.
I used to have a list that showed their radio designators and locations on a statewide map but I'll be darn if I can find it anymore.
Next time I go by one, I'll look and see if the old low band antenna is still on the property. They also had CB antennas back in the day.
I remember one along I-55 (I think) was blown up and I also recall that a ticked off trucker drove his rig right through another (it was unstaffed at the time)! I think that was also on I-55 and may have been the same one they blew up before or after it was rebuilt!
That was years ago though when the scale buildings were just little shacks barely big enough to hide a patrol car behind.
