Piper likes to go on rides and he tries to herd other riders, according to his owner.

He also likes to play at rest stops.

And Timothy is happy to oblige.

Piper, on a ride.

Bliss.

This guy and his dog were a fixture along the STP route. We encountered them several times. One of many cool sights along the way. The unicycle guy was another; too bad we got no photos of him.
