I live in a horseshoe-shaped valley, with mountains on three sides. There are multiple mountain passes coming into the valley, and the one side without mountains is basically open to the Pacific Ocean.

Go out in the wrong direction at the wrong time, and due to the way the winds swirl around, you can quite literally ride into headwinds all day long, with the wind never at your back.

Add to that the fact that as winter approaches winds blow down from the High Desert at +40mph, and there can be days when you just want to say, "Nah. I'm gonna stay in."
