With 2.0.0, alternative summer textures and Local Weather 1.0:
From Portland to Rainier:

Approach to Rainier:

Passing by...

... and into the plains.

With GIT and transition effect shader:
Approaching Mt. St. Helens...

... and crossing over toward Spirit Lake

(somehow, it doesn't look quite as nice with the GIT shaders than with the alternative texture package...)
And a few problems:
Artefacts in elevation - probably a tile boundary:

*Really* interesting airport layout...

All in all, it came out very nice - in my view, we just need to focus on an advanced texture set to get things really impressive... but that's hardly your problem
