How about the dumbest one "with luck" I ever did, not too long ago? Got a free junk boat and trailer. Hooked it up, no lights decided "I'll risk it" about 15m from home, but I could mostly stay off the freeway. And it had no safety chain, the one "loose" one in the truck did not seem to reach.
Off we went, maybe, 3? mi or so. YOU COULD NOT SEE the thing in the mirrors as it was narrow, and the little camper, etc. I was on a straight section of town into Post Falls. Finally realized IT WAS NOT THERE. Went back maybe 1/2 mile, nearly decided it was gone....someone else dragged it off? Damn near A MILE back there the stupid thing was, coasted harmlessly to the curb (35 zone) sitting there "waiting." The receiver stinger was REALLY short, I had stuck it in, then pulled it out until the pin went through.....COMPLETELY BEHIND the stinger!!! The SECOND time, I GOT THAT CHAIN to hook up LOLOL
