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.

It's actually a trifecta of the infamous Value Added, Penthouse, and Larvicide.
