When I think about teenage punkers harming creatures, I get into my "vigilantism is the only way" frame of mind and my wife tells me "take it easy" but really, what's to be done? Once I saw an obnoxious young couple throwing rocks at ducks and I went up to them and quietly said: "Stop that right now." Luckily for everyone, they did. But I worry. What kind of tortured maniac throws rocks at ducks, owls, etc?
