Rather than giving you pictures, I've decided to map out the 3 fixed courses. U means Up, which means after you pass either a windmill or barn, you should go up in order to miss hitting the windmill. D means Down, which means after you pass a windmill, there's a barn you need to fly into next. This is for the perfect, shortest route and doesn't cover any barns you may have missed. Got it?
