I've only done pieces. I don't think I've completed an entire section even. Eventually, I'll do the whole thing but I'd love to hear about your favorite spot, obstacle, or view.
My favorite spot so far is Chumstick Mountain. The road up wasn't difficult, but required my attention. The best part was that the views were absolutely magnificent.
Chumstick is an awesome spot! Bethel Ridge is also a great but it seems to be getting way more popular these days. I like the Loop Loop Forest and Skull & Crossbones Cabin area.
