Here is the gps map of the park. It's better than the CCC map with the stars, but the trail is so close to itself in several spots even this is not completely accurate, but it's a little better representation.
At my last meeting with the park it was mentioned that they were going to change the main sign to the park and actually add the trail map to it, but that was years ago and nothing was ever done. Everything with this park has to be approved my the board of trustees and Jackson seems to be really against having anything that actually gets people outside to do anything.
I was once told I couldn't even fix a washed out section of trail with a reroute without having it approved first. It's funny because I bet none of these people who make decisions could even find the trail.
My favorite part of all meetings with the park though had to be when we (MMBA) were told we could not alter the trail in any way because it was a beginner family friendly trail and they didn't want additional features that people would not be able to ride. This trail would be one of the worst places in the area to introduce someone to mtb riding. They also made a comment about the dirt jump area and how they know it's there but choose to ignore it.
