I just returned from a daily bike ride around the loop.  

Has anyone else noticed how many little black bags, neatly tied at the top, have been left on the side of the trail?  What's up with that?  I don't know whether a person who leaves their dog's waste bag on the side of the trial, does so accidently, or if they do so intentionally.  

It's great to know that "some" people actually do clean up behind their furry friends, but cleaning up a mess, depositing it into a waste bag, and then leaving the bag behind, should be unacceptable by most standards.
