You definitely need a camera for this one. The views are worth the trip!
I'd come prepared with a camera, a bike with 5" of travel, good brakes, and nice wide tires. The descent is shale'y in places, kinda sketchy in places, and awesome the whole time. The climb is fun, 100% ridable, and keeps you on your game. If you're an advanced rider you can probably clean the descent without problems. These tech downhill sections are easily walkable. The views from Prairie/Minor intersection are worth it.
