You'll get in trouble with the natives if you refer to it as "Frisco". The preference is San Francisco.
I, along with another person I know, downloaded the Mt. Shasta scenery that is available for free. I made one flight and then deleted from the HD. The other downloader, a real life pilot who knows the area did the same. Making weekly trips up and back along I-5 for three years gave me a pretty good feeling for coloring and the Mt. Shasta scenery was nothing like I remembered.
As it would be difficult for me to render Italy, the developer's home area, so must it be difficult for him to render California. I know the source of his source and when the area was sourced. Not being aware of the climatological history can lead to oversaturation of the material.
My solution to what I feel is over-hyped scenery is to download all the source and make my own scenery. It's turning out rather well. But it is a large project that is taking some time. Northern California is almost done and the source for Southern California is 80% downloaded. As to be expected, there are many airports not where they are suppose to be, so they get moved and redone. Plus I'll add some objects to make them more life like. Eventually (maybe by Christmas?), I'll have the state and it's 500 airports all sitting pretty.
