I was a mechanic most of my life, with a few years off to be a mad scientist. One summer years ago I worked on big rigs and occasionally I would have to move some behemoth off, then back on, a lowboy. So I figured, what the hell, now I'm sort of qualified to move about in these things. Wrong, wrong, wrong.
And this wasn't a backhoe, this was a full-on, humungous, crawls on tracks excavator, which my neighbor offered to rent me "if I could run it".
It took at least a minute and a half to figure out this was not going to be something I would successfully accomplish soon. As I said, ya hadta be there. It was fairly horrible.
Fortunately no actual damage was done, and I tucked my tail between my legs and got someone with a clue...not me!
