Luke is the only male Asian elephant to interact with the public (although I believe Bo may do meet in greets before and after shows?).
However, Butch a castrated African from EARS does interact directly with visitors, as does George (also castrated) at Wildlife Safari who participates in an annual visitor car wash and grape stomp.
As for my opinion, tschandler71, I am respectful of both approaches, and would be willing to work in environments with either. With that being said, I feel PC is a more modern approach at elephant management which does not require a domineering relationship (regardless of what other professionals say, working FC with a 8,000+ pound animal requires dominance to some degree). But as I said before, FC seems to be much more effective, but due to the emotional nature of elephants, in addition to safety concerns, I applaud the AZA's 2016 mandate of PC in all of its accredited facilities.
