My 3 caches that require a significant hike, the hint is truly a spoiler. I realy don't want people hiking for 1, 4, or 12 hours, just to log a DNF. The one super spoiler I made sure to mention that fact in the description (http://coord.info/GC1NPJV). I had a few DNFs on that one, and was sad that people had made the hike, and were unable to bag the cache, so increased the spoiler-ness of the hint.
My caches that are not so much of a hike, I have more vagg hints
I agree,
