I've been walking, running and cycling on this trail since its creation, and while it is better than nothing, I find that the Greenway has some definite issues compared with other similar town Greenway Trails withiin TN and other states I've lived in.
With its proximity to Mouse Creek, and various low points going under roads, it is very prone to flooding at multiple points. Can't tell you how many times I have had to leave the trail to "portage" via roadway or other means. And when the water subsides, it leaves piles of trash, debris and a muddy mess.
There is also very little adherence to guidelines by cyclist vs. pedestrians vs. kids on scooters, the picking up after dogs, loose dogs and other problems. I've seen accidents happen on more than one occasion due to collisions, etc. On weekends and other busy traffic times, I avoid using the trail as it is more of a headache than it's worth. Cyclists not yielding to pedestrians, kids/people not paying attention, dogs lunging at each other....
But one of the biggest and most recent issues for me (personally) is the increase of transients and homeless people making it a hangout at various points. One person (or more) even set up a ramshackle shelter and encampment off the trail near one of the marshes - the area behind Lowe's. I've heard parents complaining about some of the people hanging out near the playground and loitering in the pavillion. I've seen guys who seem to be living out of shopping carts and plastic trash bags, set up "camp" for the day directly along the side of the path. While some of their activity is not necessarily illegal, some of their behavior and possible instability (from whatever source) is troubling. At least one man, talking to himself, appeared drunk or on drugs or mentally unstable - or all of the above. He may have the right to be there, but it does not make it an appealing place, or feel like a safe place, for me to walk/run/cycle.
As a single woman, it makes me increasingly uneasy to be on parts of the trail that are not exposed to roadways and public view, or are within the more secluded areas like Tinsley Park. I think its only a matter of time before some kind of assault occurs, especially given the increase in vandalism and crime that has been documented with fixtures on the Greenway, and at businesses/property along the Greenway.
