Riley & Murphy: The Rock!

I do not know what it is about this rock.

 Maybe it smells great, or just the right shape to roll with your nose. For some reason Murphy stops to check out this little pebble EVERY day if he can spot it. I literally have to drag him past it in order to continue on our walk. Whatever magical powers it holds over Murphy takes no effect on Riley. He could care less about the pebble.

The thing that amazes me is that this pebble has remained close to the same spot for about 3 weeks now. This thing has made it through rain storms, wind, and even ice storms. Maybe Murphy knows something that I don't.
