Greek demigods avoid the west because of the power amount of Mist. It is also where Mount Othrys is, which is the home of the Titans, Camp Jupiter is in the west, and so is the entrance to the Underworld. Not to mention that CA is pretty much the farthest away from camp you can get (besides Hawaii and Alaska), so it is hard to get back to NY or call for help. Basically, for a Greek demigod, the west is just bad luck.
