Our youngest daughter was talking about a petting zoo on their property in south Florida. And she was talking about getting some small horses. I think she did get one. I tried to talk her out of a petting zoo, though, as the liability was too great. Cute pony! She'd love it!
Sorry M.B. - I had finished a long comment and it all disappeared! Anyway...to respond to your question: I don't think our daughter ever got the petting zoo underway...too much work, too little time, and too much liability. We haven't been down there for awhile for reasons of which you are aware but she hasn't mentioned it, so I'm sure the idea has been discarded or put on hold.
