I've done frost patrol in a 500 over avacado trees.
There was a time when I was hired to look for someone's lost dog.
Another time I was hired to look for a gang of white line painters who had apparently stolen some guys wifes handbag. (I didn't ask - I just flew)
I've also gone out and looked for crashed radio controlled planes - some were found some weren't.
And I also remember having a guy phone up and wanting to drop 10,000 ping pong balls over a crowd at a skateboard competition. We politely refused that one!
