Early autumn is great. It's relief from summer heat. It's colorful leaves. Late autumn sucks. There's too little daylight. You need outerwear. The trees are bare. I hate bare trees. They're depressing. It might as well be winter.
However, bare trees are one less thing to bum me out in the desert, since there aren't many trees to begin with. The plants here might threaten to stab you with thorns, but they don't depress you with their nakedness.
