Funny this should come up- I rode the whole of Potrero Rd. today (going east) and just about had a heart attack several times. It's described as
averaging 9.7%, with max grades of 15%, but I saw 17-18% a few times on the Garmin. Then, I had to climb Westlake/Decker back to Mulholland. That hurt.
I realized, though, that the sole purpose for riding grades above 10-12% is to make the 7-8% grades feel easy.

It's only decker from the Malibu side. Decker ends at the intersection with mulholland highway.
How did you end up all the way out to potrero? Did you go around pt mugu?
I guess that means you did potrero and old potrero... I assume you are talking about the top of the first one before it turns into Lynn.
I was on potrero today also, but it was just the old potrero part that drops you into hidden valley.
