Nope, no survey needed.  Just use your common sense.  California has over 39,000,000 people and it's land mass is over 160,000 square miles vs 600 for Oahu (lol).  Are there unreported incidents in all of Hawaii? Absolutely. Do you want to argue what the difference in what that number might be? Or are you good?

My suggestion - go back in the water or picket on Mauna Kea....things you probably do best.

Suggestion #2 - head to the library and study how to sharpen your obviously very dull common sense.
