Laguna Seca

Motor cycle track day (apparently every day is booked with something unless the track is preparing for a big event):

 Top of cork screw.

 It is much steeper than it looks in the pictures.   It goes down the side of a mountain and looks more like a ski slope.

 Under cork screw tree.

Note for future visits, Laguna Seca is in a county park and is open to visit every day unless they are taking tickets for a big event.
