The weather in the Bay Area is essentially perfect. The scenery is beautiful, and you can see the ocean, the desert, magnificent forests and the mountains all in the same day. It doesn't get too hot, it doesn't get too cold, it rains only for a few months out of the year, and it never gets very humid. Living in the Bay Area makes you spoiled and lazy because it is too comfortable. As the piece [1] by Mary Schmich (and again by Baz Luhrmann) says, "Live in Northern California once, but leave before it makes you soft."
