I tried riding up Rollie once. ONCE. Anyway, finally tried CA - at least part of it. I started from the "top" and turned around where the trail loops back and almost touches a previous section (right before a steep roll down) as I didn't want to miss the nice flow of the purple reroute descent. Definetely skipped a couple of sections out of fear but they seemed like more guts - that I didn't have - than overall technical ability like lumpy bumpy. Not sure how the trail progreses after that point but I'll find out. Trail was in great shape - obviously been worked on. The park is in mid-summer drought conditions. Really strange!
