Hi there, I'm looking for some guidance when it comes to protecting open air animal exhibits from visitors' personal objects falling in. For instance, do you use any type of netting or plastic barriers at/under railings? Open to any conversation and ideas, successes and challenges. I did a quick search and wasn't able to find a thread already discussing this, but please direct me if I've missed it! (Including any hashtags I could follow to find more information). Thanks in advance!
