I do not know, I do want to meet the peoples that are building them, they can and they will (not worth stopping) as Quarry is that place.
But the point of this work day is to clean up trails and buff others so that ALL can ride and can avoid the dirt jumps. THere is a lot of trail there to be ridden on a DH or Full Suspension. Dirt jumpers can have a few lines. Plus there are lines that used to be there that could be ridden on big bikes, lets bring those back and add variety!
Come out and bring others, hoping some of the dirt jumpers are going to show up to help as well.
And yes there are a few sketchy lines out there right now that need some help to make less sketchy
