A Secret Area
Drive all the way to the airport and drive around the airport building. Here you will see a lot of people sitting down on this grass area with a lot of chairs when you get there face east. Then turn left and the airport building should be on the right of you when you are done that drive on the path on your left. Then you should be under little sections of shelter with heaps of poles next to you, then hog the wall until you slowly start to go in. Go very slow or you will fall into water. In the secret area you can drive in a space and see everything which is going around you.
