I believe that the state is trying to be responsible ... I would suggest at this point if clubs where formed in MOKULEIA, Hawaii that carried insurance and were responsible that should solve the problem.
Reopening the wall would solve the problem too. Again why don't Hawaiians select surfing over climbing as too dangerous?
That's a rhetorical question, right? Imagine Hawaii closing their shores to surfing? It's so ingrained into their culture, economics, history as to be a cornerstone of their entire society.
I suppose they'll do their due diligence, and eventually reopen the crag.
