      Unless I missed it, this trail is a dead end due to construction.

      Sky Pilot is the best option when the fences are up, then you can climb back up at the PA Upline to bypass it.

      I've been noticing this happening more and more! and not just here but other sections too.
      Always at the crux section where you had to use a bit of technique and finesse to make it without dabbing. All made too easy now.

      If the person doing this is reading this: if you simply must make the trails more like road riding, do it by _adding_ dirt. Or even rocks. Seriously: it will have the same effect, and when you finally decide to take up riding in a velodrome where you belong, the rest of us can at least undo your hack-job attempt at trail maintenance and enjoy the trails again.

      I know multiple people are on the look out to catch this punk...I think we should make a small signs and place them in location where he chopped out the challenge to let him know...maybe he is not on those platforms(most likely he is)

      A sign is sometimes a good idea. You'll most likely never catch the person.

      I had a similar thing happen on a local trail; people where cutting a corner by like 10 feet, just to avoid some roots. I'd pile logs and trees over the shortcut, but within days they'd be gone. Repeated this process 2 or 3 times before I printed up a sign, laminated and tied it to a stick over a new pile of logs telling them to screw off.

      They must have got the hint because that pile of logs is still there a few years later.

      Yeah I think it was because of the name, they just decided to merge the 2 instead of changing it

      Not really a black diamond trail if you enter from the bottom by the bridge as opposed to coming in from the highline (which is trickier). A lot of pedalling with few features, but worth the ride if you wanna hit PA which is a classic.
