I've got an old Chevy 1 ton, Dad bought it new. I've been hot rodding on the thing for years. Eventually it had an LT-1 350 Z-28 engine I hopped up in it. Dad had this thing for bumpers, and built a front bumper out of 1/4" wall 4" steel tubing, with 1/8" wall 2" tubing for a grille guard. I was on call for emergency repairs one night, but being around 21 years old, I decided to slip off and see my girlfriend, well out of my zone. It was about 1:00 AM when the pager went off, and it went off twice before I heard it. So after a 5 minute good bye kiss, I jump in my hot rod 1 ton truck, I take off down a highway I know well, just plain hauling ass, about 100-120 MPH. Just as I topped a little "whoop de doo", there was a huge Holstien cow. I hit the cow without having a chance to hit the brakes. I hit my forehead on the head liner, and both my thighs on the steering wheel. I bet the cow flew 20 feet. It didn't put a mark on the truck. Stunned the Hell out of me. I got out, looked the truck over, saw it was okay, the cow was dead in the ditch, and I needed to get gone.
No one claimed the cow, since they'd have been responsible for any damage done by their livestock in the road. But several people wondered openly what the Hell hit a cow and knocked it off the road and then drove away.
I was sure sore for three days. It was several weeks before any one put 2 and 2 together, another farmer I know and worked for said "you know, you've got about the only thing that could hit a cow like that and drive off".
