For me, returning to Los Angeles annihilates the memories of where I have just been with an astonishing speed.
Seasonal change in Los Angeles is often a very subtle thing. It's not as if we finally stop having to shovel the snow out of our driveways and can put our parkas back in the closet.
We city dwellers, we residents of Los Angeles and the surrounding areas, are for the most part urbanized to some extent. We know deadlines, start times and traffic.
