I like how it brings the best of summer and winter together (at least here in California). Bright sun, brilliant blue skys (all the smog has blown away

) and the smells. Nothing like the crisp fresh smell of the air with the faint smell of wood burning fireplaces at work.
Unfortunately, there arent a whole lot of trees that turn. There are some and they are spectacular, but it seems that lots of trees just go from green to brown then drop the leaves. In the central valley of CA tho, its a different story.
