My brain-bucket is off to those who are in charge of maintaining the bike/pedestrian paths - particularly the Greenbelt - in Boise.
Compared with, say, 5 years ago, they do a fantastic job of quickly getting the snow and mush cleared away. Perhaps it's because they've come to recognize that it is not only a recreational path, but also a significant commuter path.
Snapped on Jan. 7, near "Quinn's Pond" (click on the photos for a bigger view):
By contrast, here's what the Greenbelt looks like just across the river, in Garden City:
Garden City is proudly ANTI-BIKE. But it should be noted that there are a lot of bicycle and foot tracks along that untended stretch of path. It gets a lot of use, just not much care.
(For those who aren't familiar... Garden City is to Boise what East St. Louis is to St. Louis, or what The Bronx is to Manhattan, or what Shelbyville is to Springfield.)
