Keep On Truckin

I was pushing my dad's wheelchair down Main Street opposite the Riverside County Courthouse, which is a pretty quiet street and had just been freshly paved.  I shifted my grip on the handlebars and noticed the chair kept rolling without my push.  I held my hands off the grips and it kept rolling at about 2 miles per hour.  I stepped back from the chair and it kept moving forward.

So I walked off to the side and talked with Dad as he rolled gently downhill.

It took him about three minutes to realize nobody was holding his moving wheelchair.
