A saying I heard from my first college ag teacher:puppyluvr wrote: As a teenager, while hunting deer with my younger step-brother Bobby, I witnessed him urinating on an electric cattle fence...
After the convulsions went away, and the screaming subsided, and I quit laughing enough to check, he seemed to be OK...
"There are three kinds of people in the world:
Those who learn by reading,
Those who learn by seeing,
And those who just have to pee on the electric fence for themselves."
A little thing he mentioned: the wrong way to test an electric fence for current is with the inside of your fingers. Besides the shock itself, sometimes the current makes your hand curl closed around the wire. A trick that's sometimes helpful is to hold a blade of grass near and listen--if your ears are good enough! If you must use your hand, use the back.
Also, it's annoying to have a mower that won't turn off when you release the handle: there's a small jolt when you disconnect the spark plug to stop it.
But my biggest oops was the time I drove through a "puddle", on the downhill side. I thought it looked reasonable to cross, as I always had managed to do so previously--until my car stopped 1/3 of the way across. Wading across a hundred feet of knee deep puddle is not fun; less so when it's in pouring rain an hour before finals...
(Nothing like a jumpstart and starter fluid in the air intake to get it started again!)
