The leg description is not vague at all to me. It says thing like fly from start to point A, to B, to C, to D, and then to airport/strip E, and shows you a picture of what the E looks like. Even if B, C, and D are cities with airports, why would you ever land there when the picture of the place is not shown? Each leg is as simple as keep flying till you run out of waypoints described and see a place that looks like the picture. Since the legs are less than 30 minutes long each typically, why bother with landing anywhere in the middle?
