You can install the freeware mesh for the Alps from Holger Sandmann if I remember correctly, and the FS9 landclass for switzerland called ebch3tot.zip. This will make Switzerland much more interesting to fly, especially for low and slow, or gliding etc...

Then, still with Holger Sandmann, you should get the Bella Coola freeware scenery, which will make the area much more interesting to explore

Finally, install the "snow dog tours" packages, it will add some nice airfields averywhere in Alaska, to flying there will also be much more pleasant.
