DO WHAT smart national and state parks on the mainland do. CHARGE A FEE, you bunch of inept (D)onkey !mbeci!es 

Other parks charge a fee of say $20 and FORCE you to sign a release of liability to get a permit to hike steep and dangerous areas and the funds are used to maintain the safety upkeep as much as reasonable. Here are some examples: Half Dome in Yosemite National Park, and many Grand Canyon areas also charge fees and force you to get permits for limited and deemed riskier adventures.
