One of the new carshare signs springing up around the city. (At right is a blurry shot of the other side of the same sign.) These new signs mark places where you can pick up (or drop off) a Flexcar or Zipcar. The city has recently made many more prime parking spaces carshare-only spaces to encourage people to use these services and thereby reduce road and parking congestion. Seems like a good idea to me.

I also think these signs are just cool!
