Once hit a swarm of katy-dids going about 60 pulling a horse trailer. Had to pull over RIGHT NOW and stop. Completely blind in about 5 seconds. Scared me to death. Took 30 minutes to clean a 8" square so I could see to drive. Drove very slowly with flashers on for about 20 miles till I could get to a gas station where I could wash them buggers off. Took about an hour to clean off and you could still see markes on the windshield. Some one should look into making glue out of them suckers cause they sure do stick!
If you can't see you shouldn't be driving!
