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


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


yeah, from Old Catalyst to Party atmosphere.
likely merged bc of the name

Some looser chopped roots on key climbs...rooty switchback as you enter ol Rimjob...than on PA Tremco climb. You will never do those climbs punk...paved is for you
[Reply]


Seriously… I was just getting the hang of tremco ffs…
I noticed the same thing on some of the foreplay switchbacks too..

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.

...its one of 3...looser newbie, strava champ, or gravel warrior to pass easy.
Regardless...STOP this sh.t...and pray you wont get caught while you hack away our fun. Dumbing down to match your dumb self...f off already!

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)
[Reply]


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.

Glad they did not merge PA and C. Would have been a nightmare
[Reply]


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


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.

[Reply]
