RE: HMC Question - UPS issues -- MIDRANGE-L

LOL

Actually, I've compared by mind to the garbage pail John Steinbeck had in the back of his truck in _Travels with Charley_. He hung in the back, put water, his clothes, and soap in it. While driving, it shook as you'd expect, and his clothes were all clean by the end of the day. I just keep shaking my head and good things come out! And most of them clean!

Vern wins the prize!  Mho is indeed the old common term for units of
conductivity.....  It's also known today as siemens (S).

Vern, just what DO you do with all that useless knowledge? <g>  I'd guess
trivial pursuit is a piece of cake (or pie....) for you.

Is that Larry, Curly, or Mho?
