I'm in Utah somewhere south of Salt Lake City (the state capitol). The numbers aren't great, but they're far better than some places I've lived here. As a kid, I remember biking for 20+ minutes to make it to a small supermarket.
EDIT: as others have said, my paths can be quite bendy at times, but it's different than many suburbs in the US. Salt Lake City (and, by extension, most of the valley that it's in) is built on a fairly rigorous grid system. We have lots of straight roads with large blocks (in some cases, it can be 1-2 km between lights and crosswalks). We don't have too many ratfucked suburban mazes, so the walkability problem here is primarily due to sprawl and a dearth of crosswalks.
