Is there a good source of information about the RMZ that gives any detail about why it's not great other than it being part of ZAA? I've seen people say the Richmond Zoo is bad but never really give any explanation as to how they got there.

My mom has a membership because she lives down the road and loves going on walks since the hills are good exercise. We've gone once and my daughter was overjoyed at seeing all the animals. If I knew there was mistreatment of animals or something else that would give me pause I'd want to know about it so we wouldn't go back and I would tell my mom to give up her membership.
