Saw an interesting sign at the Devil's Fork Gap trailhead. It went something like this:
Hikers! Please don't let dogs follow you. These are people's pets! A little boy lost his dog because a hiker let it follow him to Sam's Gap and it got run over crossing the road.
Now maybe it's just me but I think that's a pretty unreasonable request with the obvious right answer being: Keep your dog at home.
Have you ever had a dog follow you? How did you handle it?
Finally... I volunteer with the local humane society and this year I brought 3 lost hounds and 1 dumped pig off the trail to the shelter.
