You thought this new decade was just about terrorists and war and lying Republicans. But noooo: This is also the decade in which we begin to phase out swimming pools with deep ends. No kidding. Mark Morford, wackjob columnist for SFGate, usually the sort who is off the deep end, has something to say about this.

I have such fond memories of swimming lessons from my childhood. I don't know how many summers had swimming lessons as a major component. At least five. And I know exactly what Morford is talking about. I remember triumphing over the deep end. It changed from a Dangerous Place where I was not allowed to an area I could splash on out to, turn around, and look across the pool to the kids who couldn't yet tread water. There I was, and there they were. Kids. Growing up.
