Your wife is right! And for the most part we do, which may bewhy not that many "locals" have posted here.
I'm just posting to remind everyone of the bigger picture. In our short (less than a year) time in geocaching, we have found the Hawaii caching community to be a very responsible & responsive group. I could provide you several examples where hiders voluntarily archived or moved caches that were thought to be in dangerous or other wise questionable locations. But that would be boring.
Seriously, can't we assume (dangerous I know) that geocachers are responsible folks who don't encourage fellow cachers to break laws to find their caches? Having said that, we all have different comfort levels. We have aborted searches for all sorts of reasons: from we were uncomfortable in a deserted area, to we prefer to do that sort of rock climbing with a harness & protection... When we turn on the GPSr we don't turn off our common sense right?
The bottom line here is that the placement of this cache has been discussed locally and approved by the reviewer. If the OP believes access to the area should be restricted, then he (and anyone else who feels that way) can simply elect not to look for it.
