Just looked out into my backyard that is joined with the neighbors' since we don't have many fences. There was some guy with no shirt sprinting up the hill towards the road and the woods! I rushed to the front door to see if I could help him, and there he was at the edge of the woods panting and looking a little beat. Watched a little longer and he walked back down the hill and did it again. Whoops!
To make it actually PR, he's an equine vet! (a really hot equine vet)
