When we lived in San Francisco, the city opened a brand new dog park on a patch of dirt along a freeway just a couple of blocks from our apartment, so we were some of the first (and often some of the only) ones to use it.
We went there so often that I was its Foursquare mayor until we moved to another neighborhood.
