I think it was the lady's husband who complained about the plants infringement on his backing out of their driveway. I guess he complained about that and then the wife complained about other things and Barb didn't address it and the fines kept piling up.
Barb's garden went all the way out to the street and those plants were 8-9 ft tall, at least some of them. I know the HOA/complex where we live owns at least 8 ft from the street. It's your yard/lawn, but they own that piece of it. That is why I never plant anything close to the street level and I do understand about having obstructed vision when you are backing out of a driveway. It is a steep curve in that section.
I just hate it that that happened to her. She has the most beautiful garden in this whole complex.
