I once dodged a spare tire and wheel coming across the median about 70 mph. If it had been dark out, or I had been daydreaming, I would probably be dead.
The weirdest thing was a wreck I came up on, there were 20 or 30 frozen dogs and cats all over the intersection. Most were in clear plastic bags. Supposedly they were uthanized, frozen and being shipped for disposal. I have a soft spot for domesticated critters, so hope to never see that again! Probably wont! Firefighter
