drive!
After lugging my camera gear and tripod down to the beach to photograph a sunset I'd seen the previous night, I was greeted by a cloudy sky. I tried taking random shots, but the lighting was awful, so I left the beach. As soon as I saw this corner in the road, I had a picture of this shot in my mind. It took a couple tries to get the angle right and to wait for some cars to pass by, but it made the whole trip worthwhile.
