If you go on Mesa Grande Road, be on lookout for a very wicked right hander coming from Dudley's at location B on this map (

The problem with this corner is:
It is on the back side of a rise in the road, so you can't see the turn. The general geography and the overhead powerlines conspire to make you think the road dives into the valley straight ahead. It doesn't. There is an abrupt right turn less than 100 ft after the rise. The outside of the curve is a nice little bowl that may or may not require a tow truck for extraction.
Most of my activity up there is has been on motorcycle, so the turn is a little easier to see. Once, I was up there in my 914, and I KNEW the corner was up ahead. I was going slow(er) and I still missed the turn. I tried to make it but spun the car off to the outside of the corner.
