Probably really due to
a) people trying to throw stuff into the quarry and missing, or
b) based on the poster’s identity, from aiming his shotgun at Bugs Bunny and missing.
Or drove behind coal trucks in eastern Kentucky.
We lived high on the hog in Prudhoe Bay - just leave the truck running round the clock. Never a problem with ice on the windshields.
But with nothing but gravel roads, frequent (like, several per year) windshield replacements were a fact of life.
Fortunately, our employer took care of keeping our tanks full, and provided very efficient windshield replacement services.
I’m assuming this is exaggeration, no? A lifetime in the Chicago area, and I’ve never needed 15 minutes to clear enough to drive.
Please come visit me in Saskatchewan in mid-January and learn how the other half lives.
