Problem stems from those who have this hike in their bucket list. I've seen idiot visitors hiking with rubbah slippahs and get offended when I tell them that the trail is slippery and dangerous. Many have an entitlement attitude without any courtesy or respect for the residents in the surrounding area. Leadership on this island panders to cry babies at the expense of law abiding citizens. Post the illegal sign and fine and enforce it. Otherwise it becomes another Laniakea, signs everywhere and no enforcement.  Firemen should not be risking their lives for stupidity or hikers too lazy to walk down.  Need medical attention, call Medevac and they can pay the exorbitant fees. Law and order will solve this nonsense.
