Runners,walkers and cyclists need to know the rules of Riverpark. Stay on the right side no matter what and nobody has a problem. I don't know Mr. Lastines habits on Riverpark, but if a cyclist need to call out, is he on the wrong side of the path. The majority of the people who have no clue about rules where to be on the path are families with children on bikes and persons out only a few days during the year. These persons don't control their children and can barely keep from crashing themselves. I give runners and cyclists as much space as possible. Educating the users of Riverpark would solve many of Mr. Lastines concerns.
