How can we protect Native American ruin sites?

I wish I didn't have to make videos like this, but here it is. Someone went to the Sedona Subway Cave and knocked down a wall of the Native American Ruins there. This is why we can't have nice things.

Anyway, I try to give people the benefit of the doubt and hope that lack of eduction is the problem in cases like these. So Eric and I decided to put this video together in hopes that it will reach someone and change their point of view. I am no expert and won't pretend to be, but if we try our best to use some common sense and practice respect for these places we love, it can't hurt.

So anyway, I hope this helps.
