Rocky Hill Walk

Keith and I took a walk up Rocky Hill this afternoon.  We do this for a change of scenery and to work our uphill and down hill muscles.  There are a fair amount of walkers and bikers who do this stretch of road.  Cars also take it to enjoy the scenery.  What I always wonder though, is why do people dump their trash out in an area that they go to for its beauty?  Wouldn't they want to keep it unspoiled?  That really bugs me!
