A deeply red/Republican and relatively low-density state might seem like a strange place to find a functional public transit system. Utah is an interesting place. The geography of the Wasatch Front lends itself to public transit in ways that less geographically-constrained places do not. The region is mostly a north-south corridor, with occasional off-shoots to the side, which is how the transit network has developed…
An aside, smog is really bad in Salt Lake due to its geography and that is probably one of the reasons they are taking this so seriously.
