Description

There are many fun challenges on this short section of Grand Slam, some with walk arounds, but not all. You might want to scout it, then ride it again.

Chances are you rode in from StormKing, ELV or KGB, which are all pretty nice and flowing. Wake yourself up for this section of the trail cause there are some challenging rocky technical hurdles, i.e., don't fall asleep. If you came in from VooDoo, you are probably pretty alert already.
