I dropped off a copy of the signage requirement with some suggestions at the Lincoln Children's Zoo today. Also mentioned that they are only keeping law-abiding citizens out and not criminals. Since we're members I left my name and contact info if they have any questions. Will be interesting to see if they respond. My issue is that the sign at the front entrance is not clearly visible when you are approaching or entering through one of the other booths not connected to the gift shop. Well, that and the fact that they are posted at all, but I digress...
