Hoa’s are on a power trip

This was years ago when i used to live in a town house community. My mother owned the townhouse, but there was an hoa. We had probably a 5x8 concrete pad as our backyard. The townhouse was open to a main road as well. But nonetheless, we weren’t allowed to put up fencing over 4 ft around our “patio”. My mom tried to put up a bamboo fence to block the road and weird people that walked on the main road (not a very nice area). They actually called the police because she refused to take it down. The cops broke the fence and we moved shortly after.
