The name stands for Cash on Delivery, appropriately named, because this one delivers. It's a fun flow trail, with plenty of technical obstacles. The trail is heavily forested, so scenic horizon views are minimal. But you'll find an excellent trail system with technical (large lava rock sections), banked turns, and lots of fun sections.
Also, Dirty Pirate can be accessed from C.O.D. (definitely a challenging terrain park of sorts.)
