David Paulides new 411 Ufo could and probably touches on this compared with his other observations for missing hikers. He's strayed from trying to say this but when evidence points in one direction for the most part..

Cause these people just vanish from their spots then are found later in really hard to reach places most people just wouldnt go to on their own. Not to mention the earch dogs ending up with a big fat nothing.

I still have to watch the new ufo 411 sounds really interesting. The mothman stuff was from decades ago and as far as I know hasnt been anything since.
