We left Springfield at about 1440 hrs after DH's "procedure" and, just the other side of Republic (on 60, of course) there was a MESS of these-two-or-three-skidded-off-and-every
We had been going the limit and that tried to change abruptly. It didn't change as quickly or smoothly as I'd hoped/planned. WE went skidding around another skidding car with me pumping the brakes and babying the steering wheel and went between that car and a post and something else and back on the road. And when the adrenaline wore off I had a good shake and a few tears (we were in a parking lot by then so I could). And when we get back on the road after the little dance everyone was pretty happy to do 10-12 MPH the rest of the way. No crowding, no attempts at passing.
AFAIK, no-one was hurt in that first slide-off, but Ah-dunno about the 12-pax on its side between Billings and Marionville
SO glad today that I can decide it's too bad to drive -- ambulance drivers and such, I've got a Mala to Ganesh going on your behalf.
