Here in Zone 9 the true fall season doesn't hit until end of November to early December. This brief period is when we finally see colors other than green and brown. There's something nostalgic about really sunny but cold fall days. They give me instant happiness and peace. I should probably mention that to my therapist she'd be happy to hear it. I think it's important to have those little "happy" things. Otherwise, you're just a miserable SOB that's consumed by your own miserable life. Be happy! Don't be a miserable SOB!
Also, now may be a good time to buy a leaf blower.
