Should any pronunciation prevail or have prevailed (I suppose one has among locals), I hope its users will be gracious toward and tolerant of speakers using other pronunciations, unlike many Nevadans are toward speakers (including schoolchildren) who do not pronounce Nevada like the romanticized silver-miners purportedly did.

I have the impression that some Coloradans have become as intolerant as the aforementioned Nevadans of the old pronunciation of their state's name.
