I was behind a truck on the ACE and a tool box flew out of it. I managed to miss the tool box, but apparently, when it hit the ground, it spewed its contents, including this sawzall blade.
The truck was new and in great condition. It didn't look like it had anything in it, and the tailgate was up. I have no idea how this happened, but it did. Thankfully, I got one of the toughest FMIC cores ever built, and it protected my radiator by sacrificing only a few fins. No leaks, just cosmetic damage. That's my excitement for the day.
