[Chris in WNC]

A bright Sunday morning in 2008, enroute from Florida to the MARC/MAFCA meet in Dallas in our unrestored '31 Tudor.
Rolling through Shreveport LA on I-20, one of those stretches where the old US highway joins the interstate for a while.
Three lanes of traffic, I'm in the center lane at about 55MPH.
Suddenly about 50-75 yards ahead I spot a long 6"x6" timber laying across my lane. Looked like the ones truckers carry under their flatbed trailers.
Vehicles in both other lanes made changing lanes impossible.
In the few seconds before impact, a few of the unpleasant possibilities flashed through my mind, but all I could do was take my foot off the gas and grip the steering wheel tighter.
My two right wheels went over it "blump-blump", but it felt like the timber was only about 3/4" tall and I experienced no loss of control.
First opportunity to get off the road was at the Texas welcome center a few miles later, where I checked out the wheels and tires for any problems and there were none.
Was very glad I had just put on a new set of Goodyear tires for the trip.
