This is a fun/fast road that is a good one to hit up while checking out roads near Skyline. The pavement changes to rough half way down the road so be ready for some chunky stuff. Some of corners are blind/rough so make sure and stay in your lane while bombing this one.

Just so everybody knows the backside (red on the map) of thompson is closed halfway down due to a landslide a while back and they have barriers up in the middle of the run where a landslide crushed part of the road.
