The article identifies the turtles as Diamondback Terrapins, about eight inches long and two or three pounds. Two weeks ago I was driving home and had to swerve to avoid a snapping turtle. He was hugh and it could have been series if I hit him.
A couple of weeks ago wifey and I returned home to California from toodling around the entire lower third of the U.S. - a month on the road......countless times in the south we saw turtles inching across highways and even the Interstates. They'd be pretty visible as you came upon 'em, and we saw only one squashed version.
Armadillos, though - that's another matter.....we must have spotted a hundred of 'em, and not a single survivor.
Saw one like that a number of years ago on I-55 south of Cape Girardeau. Talked to a nature guy & he said most of them make it across although a semi could do a job on him.
