About the spookiest road I can remember driving on in my 14 years of cross country was State Highway 191. I was driving across the Flaming Gorge Dam in Utah in 1978 with a 10-foot-wide, 51-foot-long load of steel going to the dam.
There were places where taking the whole road still left the trailer tandems sliding off the road where the drop-off was probably 2oo feet or more. I actually rubbing trees with the side of the trailer in other places.
May not sound like much but if you’ve ever been there you know that road is SPOOKY!
