PSA: If anyone is thinking of riding this, the chances of a mountain lion attack on this route are < 0.00000000000000000000000000000000000000000000000001%, even if you ride it at night (which you won't be doing). It is absolutely safe.
You are FAR more likely to have a heart attack going up Alba (and the nearest defib is at the Epire Grade/Felton main fire station).
