Hmm...if he doesn't use that idea, I think I will. I'll trade the bases on the center isle for ports and make the current ports airfields.
EDIT: Motley, you ought to get an image editing program that uses layers such as GIMP (free) or Photoshop (very not free). Then you can use a transparent layer to place your field dots and another for GV spawns. Then mark the numbers down and as you're building the terrain, make a copy of that image file (naming it something different, like mine is currently Vehicle Fields.xcf and Vehicle Fields Working.xcf) and erase each dot as you place the field, saving the image whenever you save the terrain file. This way you know how far you've been set back by a TE crash, if you take a break you know where you left off, and you can even put the fields on in non-numeric order without getting confused.
