Best Bridge Coverage
For what it's worth, and it's only my opinion, Channel 5 did the best job of covering the I-35W bridge disaster. They also happen to be my TV news of choice. They have distinguished themselves before, most recently covering the Rogers tornado.
Actually, the other channels did a good job, too, but noticeably constrained by their past behavior: KARE's pithiness, WCCO's arrogance. Channel 9 would in fact be my second choice.
