Sketchy trail.
This is true but thanks to the anonymity of the internet.. it's harder to pin blame on people for this stuff. And it was solicited information and a sanctioned trail that runs through a public park.
That said, this trail could use some maintenance. It's a very technical ride to begin with and there are some spots that were extremely sketchy when I last rode it.. (November). It cuts through the periphery of an industrial yard at one point (private property) and there are some sections that are unrideable due to erosion (the trail is severely off-camber as it were, more so than the "don valley trailway"). I'd be willing to pitch in some work..
