Be careful of roads that have "buckled" because of the heat!
We were traveling up 77north towards Cambridge, OH, when we saw some State Troopers with their lights on and flares burning on the highway. Turns out they were slowing traffic to go over a 6-8 inch high bulge in the road seam. I hate to think what would have happened if we hit that at speed..
*I had just seen a vid online showing an SUV catching some major air after hitting a large chunk of buckled highway.
