Well, since there were no responses, I took a chance.......
downloaded N. Carolina. 21 humongous files - took about 3 hrs. (my first experience with MegaScenery).
........loaded into P3D no problem.
I'm kinda "iffy" on the results..........its nice to be able to fly over my house, the nearby park and pond, etc, but when you get down on the ground, there's NOTHING.
No trees, fences or structures except for very basic stuff.
It looks pretty good from the air though, and I guess that's what counts..........
