I'm watching a police chase on TV at the moment. A woman has stolen a police SUV — they say it's a Ford Expedition — and has been driving around and around mostly the same streets in Lancaster and Palmdale for more than an hour. The newsfolks on KCAL Channel 9 are locked into that awkward position of having to say the same things over and over…and they really don't know all that much to begin with. At the moment, we're kind of on Tire Watch, wondering how long it'll be before a shredding left rear tire renders the vehicle undriveable. Stay tuned.
