Is a lawn legally allowed to block a sidewalk? I know the right-of-way stretches well past the boundaries of the road. I've always walked on the edge of people's lawns when there's no sidewalk, because I'm fairly certain it's legal to do so. If there's no sidewalk, pedestrians walk on your lawn within a few feet of the road, and there's nothing you can do about it.

One thing I would never do is step into the street to walk, regardless of how angry a homeowner might be about it.
