Year Opened2012
This was built as a connector trail from Value Added to Two Stroke. Also works as a good warm up if heading to Larvacide.
At the top, there are three different lines. The left-hand trail - is the least popular. The middle trail is the mainline for riders looking for a single black slab. To the right in the woods is a double black line (signed) that requires a 13-foot drop to a slab transition.
There is also an easier line 1/2 way down that sneaks through the forest on the right. This avoids the sting of the last move on the slab.

Jun 26, 2019 from pinkbike.com
It's actually a trifecta of the infamous Value Added, Penthouse, and Larvicide.

I honestly wouldn’t call any of them pantry lines! None are easy!

Panty line? Might be time to change our language boys.

What's that line off to the left like? Worth checking out, or partially overgrown for a reason?
We hope you've been enjoying Trailforks!
