I had a few hours off in Los Angeles and found myself in the La Brea Tar Pits museum on Wiltshire Boulevard.
Over the last century the pit has been excavated to reveal the well-preserved skeletons of thousands of animals - sabre tooth tigers, giant mastadons, camels, bison, extinct condors and eagles - from between 10,000 and 40,000 years ago.
I couldn't help but see the parallels the following day at the LA auto show. It was easy to imagine the animal skeletons replaced in a future LA museum with the bare chassis and body frames of the giant SUV.
The GM stand was a good place to see a couple of these near-extinct beasts. Hummer's models had a good showing, but it could be the last time you'll see the brand on GM's stand.
