I'm an avid reader of your blog and a Noe resident. In general, I love Noe Valley, but one of the things that drives me nuts are people believing that they "own" the sidewalk in front of their house and putting gates/fences around the very few green patches of earth, thus restricting their use. I am a dog owner, and there are literally so few places my dog can go to the restroom it's ridiculous. I, like most Noe dog owners, are responsible and ALWAYS pick up after their dogs. I think it's rude and perhaps illegal for people to be fencing off publicly owned property such as public green space. Tips? Advice? Any more info on the issue?
