Moxie says "this is bullshit!" That big rock in front of her was placed to cover up the hole where I'd popped in on a groundhog. Moving the rock seemed an easy den repair, and it will be a much easier hole to open up again if I ever find this den occupies again.
The den entrance behind Moxie, where she looks like she is about to enter, below, does not seem to be connected to the pipe she entered on the other side of that wire fence in front of her. Go figure!
Misto was on the posthole side of the fence; he did his bit!
