Anyone got a line on some good/accurate Grand Canyon terrain
enhancements? I've tried the PCAviator National Parks add on and am
looking at the RealScene package as well. The PCAviator did up the
detail a bit, but not too much down IN the canyon. Is the RealScene
worth picking up or is there another that's better?

Thx!
