This is a short diary, because sometimes a picture is worth 1000 words.
The Bicycle Taliban - a bunch of "Extermeists" have invaded Santa Rosa California. The Tea Party, Car Party, Median Party, I dunno - some party type people are going to save us from these cretins.
Santa Rosa California is doing a pilot project to put in a 'Bicycle Boulevard' on Humboldt Avenue in that City. A Bike Boulevard is basically a street - not a bike path, or a street with a bike lane - designed for bike traffic. This is frequently done with calming treatments like traffic circles, removal of stop signs, and often by cul-de-sacing the street in various places to discourage through automobile traffic in order to make it bicycle centric and divert faster auto traffic to nearby primary arterials. Often this happens because autos are bypassing the arterial to use a residential street that is favored by cyclists, but they drive on that residential street over the speed limit.
A classic example is the Ellen Fletcher Bike Boulevard on Bryant Street in Palo Alto. There are several cul-de-sacs where only bikes can pass, limiting Bryant to local traffic only. Riding down Bryant you can frequently see Elementary School children riding to school on what is an extremely safe street, blocks away from high speed and poorly shouldered Alma Street. Basically - Bryant is awesome. And frankly, it's a very desireable address - the lack of through traffic makes the street very quiet and property values there are up.
Santa Rosa has some people who pretty much like to cut through Humboldt who don't see it this way. And they are letting you know!
At least in the next incarnation they corrected one of the misspellings in "Extremists"
