On a related note - I've been hearing a Toyota 4WD pickup,
with a really loud exhaust,revving the engine for some time now.
I finally went out to see what the heck was going on,& saw
the driver trying to back up a trailer with a couple of small off-road
vehicles down the ally next to our house,in the dark.It went something
like this.......
Back up,have the trailer come around too far,go forward,
Back up,jackknife the trailer,go forward...........
This has been going on for about 1/2 an hour.
