I haven't seen dog pooh hung head high. I wonder what the purpose is of that.

We do get dog owners who take the free dog poop bags at the trailhead that they need to scoop the poop into and then are 'supposed to' return it to a garbage can near the trailhead or take it home.

'You pack it in - you pack it out' as signs say at the Grand Canyon.

It's like these people are expecting the Poop Fairy to come by and pick up their dog poop bags.
