The only alternate pronunciation that drives me absolutely, completely, nails-down-a-chalkboard crazy is those pretentious idiots who mispronounce "Nevada". Especially the ones on shows like CSI who should theoretically know better.
It's Ne-vad(rhymes with dad)-a.
Not Ne-vad(rhymes with cod)-a.
I've always pronounced Nevada the second way, Sue--and so has everyone I know. Maybe that's another regional accent thing?
