I love this time of year in our neighborhood. Somehow with our microclimate we are able to support trees in their autumn life next door to trees in full spring blossom while outside my bedroom window the trees are in full winter slumber. Several places within a block or so there are maples (or what look to me to be maples) in full glorious fall color especially gorgeous red leaves right next to fruit trees (plum and cherry?) with little pink blossoms breaking out all over. Pretty darned cool IMO. San Diego was a bit seasonless and to some extent you could argue the same about San Francisco - after all our summers aren't exactly balmy! But somehow with the changing trees especially in our neighborhood I get the sense of passing seasons much more (without the ick of Boston winters or muggy east coast summers). I did love visiting Joshua Tree or other desert lands to the east of San Diego - it was amazing to see them in full spring bloom - little flowers popped up everywhere in the middle of the sand and appearing so fragile yet in reality pretty darned sturdy. It helps to be able to drive to mountains of snow in just a few hours for a few days of "winter". That is about all I need!
