I am posting here because well.. no one else does. But in southern california highway 18 going up or down Arrowhead. Now I KNOW a lot of people in the WRX world knows it because I have driven it once and in the process going up and down, took about an hour. I saw 13 WRX's. Its really fun to take your wife with you and hear her yelling about how the sign tells you that you should take the turn at 25 and you are going MUCH faster.
I keep reminding her that the sign is just "suggesting" 25mph. Obviously they didnt have a WRX in mind when they made this suggestion
