Got Neutral, but it was missing some utah valley isms that I'll slip into if careless.. for -> fer, creek -> crick, mountain -> mou'n (or other nt+vowel+n suffix, n and t are soft enough to not be there and the vowel is replaced by a pause; clinton -> cli-in/cli'n, mitten -> mih'n...), both -> bolth... The NYT one linked was interesting too, the heatmap included everything aligned and west of Utah minus Arizona, plus a bit of the northeast and great lakes areas. The NYT one was also interesting in that a few examples, like roundabout, had me think for a minute about what I'd say in a conversation vs what I expect to hear (traffic circle) in general from e.g. google maps and might say instead if primed with it.
