When was the last time?

As an ex-cop, I know there are lots of thieves. Occasionally on this forum and others I hear of people getting items stolen from the RV while camping. I've been wondering when was the last time you've been ripped off. Was it from a state/federal park, a boondocking place, or an RV park? What did you lose? What precautions do you take, by habit, to prevent thefts?
