You guys that live up north just don’t understand what happens in this part of the country. It’s not like up north. It can be nice and dry one place and a rain shower will dump enough moisture a mile or two away to freeze as soon as it hits the road. The temps can change pretty fast as well. I 20 where I live in Abilene is one of the most dangerous stretches of state for that reason. This was on a down sloping bridge with heavy traffic anyway. They had no warning. I’ve driven on that spot. 40mph would have yielded the same results. It was a perfect storm that cost lives. We don’t have enough equipment to de ice all of the places that need it all at once. It’s best to stay home but some don’t have that choice.
