Can't offer more than the others, Google Earth has good images... and
I'm guessing you'd prefer the simulator to respond in some way to the
terrain?

I've often wished that one of the 'Irregulars' would voice narrate the
playback of a long flight in SeeYou 3D. That way we get the 'why' as
well as the 'where' he flew, and a description of wind conditions en
route. When recorded as a DVD or other video medium it would be a great
way to learn the ridges before taking your first flights.

There might even be a small market for a video taped ridge
familiarization run.

None of this replaces the need to have someone show you the ropes first
hand when you get there.

But what a great confidence builder a tape or DVD would be. Do any
exist already?
