Ok, I have two contributions..
We own a salvage yard, my brother came in from the yard for something and then headed back out a few minutes later. He came back inside and said,,, "ok,,, funny stuff, where is it?" The "it" he was referring to was a Terax Loader, and if you are not familiar with a Terax Loader, they are pretty big. 25 feet tall by 35 feet long is close to accurate.
After convincing him we did not move it, he went back to where he parked it and followed the tracks. Which,,,, lead strait to the nearby creek. Which,,, was in a 30 foot raveen...
After he realized he left it in reverse, he came back and said he had a little problem.
We ended up using another loader and pretty much cut a ramp down to the Terax, hooked a chain to it and pulled it out and replaced the soil we dug out to get to it..
The other is,
I was doing a brake job on a Ford LTD cop car, when I came to, there was a hub cap on the ground just spinning around. It seems,,, that a car driving by the shop lost its hub cap and it took off like a Frisbee. Flew into the garage not hitting anything on the way except my forehead. I was wearing safety glasses, not that it mattered. It crushed them into my scalp. Cost me about a pint of blood and 15 stitches and an eyebrow as they had to shave it off to do the stiches...
