Large Stripes Of Default Scenery Within Your State

This occurs when you did not properly install all the areas for your  state. To identify which tiles you missed simply go into your Control  Panel and select Add/Remove programs (XP) or Programs and Features  (Vista onwards) and look at your list of installed MegaSceneryEarth  areas. You will be able to identify the missing missing area by the  missing number in the sequence. Then simply install the missing  area(s)/tile(s).

The only exception to this is a region in Nevada around Area 51 where no imagery is available most likely due to the classified state of this area.
