We have these in Boulder, CO as well. I like them with one exception: they are AWFUL for bike lanes. Most drivers can't actually identify the edges of their car while driving, so when they feel pressured by the sign, they'll blindly (without checking mirrors) swerve into the bike lane to give the sign 2-3ft of unnecessary space.
