The first was a GM 4104-4106? (wish I knew my GM's better)
Headed North @ exit 67 as I was getting on after loading in Sikeston.
It was going past the exit and moved over to allow me to merge.
Once I was out on the super-slab I and brought "Jet Airliner" (our '05 Setra S417 #'d 747) up to cruising speed I gently rolled on by and waved.
It was gray with a blue stripe pulling a red VW "Thing". Both bus and "Thing" had FL tags.
I'm pretty sure the names painted near the drivers window was Allen & Mary Fordham.
The second one was a RED MCI 102A3 with 3 white roof warts on top headed South about Festus, MO (around mm 175)
Just curious if either was anyone here.
