Saw this blog post and started wondering; Why don't people log DNFs? I tend to always log a DNF. Of course there are exceptions, like constant interruptions in a busy area or it start chucking it down with rain less then a minute into the search.

I also find it nice to see what caches you have tried on the map, it makes it easier to adjust expectations on the second try and allow for more time.

What are your thoughts?
