Comment: An very interesting and informative article by Mr. Arinaga.  However, it would be most informative to know how much the rescues of people who have ignored "no trespassing", "closed", "hike at your own risk / responsibility" or similar signs annually cost the taxpayers of  Hawaii.  Helicopters and rescue and recovery search parties for these hikers violating the law are expensive and also in many cases detract from the rescuer's (firemen, EMTs, etc.) primary functions.  Breaking the law, and frankly, outright ignorance is no excuse and should not be without appropriate costs to the culprits involved.
