TTFs on TrailBridge
Arnold is the longer descending trail at the Nursery. It's a flowy singletrack route with a series of bridges and culverts that'll keep your handling sharp. It ends up at the Nursery stop and from there riders can choose to climb Twins again for another run (or to ride Devito), or to return to Brexit before heading back to Launch Pad via Bill & Ted.
