I was born and raised in Wisconsin, spent winter vacations in Upper Michigan , and spent summer vacations camping around the country. My husband was raised in Indiana, where the ice storms  are legendary. We were both taught to have an attitude of preparedness. Our cars are outfitted with jumper cables, emergency shovels, sleeping bags, windshield scrapers, and (of course) umbrellas.

We don't have hammers.

When your car falls into water, you can't open the door because of the pressure from the water. If you have manual windows, you can open a window and swim out. If you have power windows, you must break a window in order to escape. How do you prepare for this? Keep a hammer in your car, within reach of the driver's seat.

The night of the I-35W bridge  collapse, I watched regular-channel programming for the first time in two years. I watched all night. By the time the rescue efforts were called off for the night, I had finally figured something out. All along, people had been saying that there were 50 or more cars on the bridge when it collapsed. But on the news coverage, there were more like 20, if that. I finally realized that all those missing cars were underneath the part of the bridge that was in the water.

Did those people keep hammers in their cars? Could I have gotten out?

There is a running joke in Minnesota that all we can talk about is the weather . There's a good reason for that: We have a lot of weather, and it causes the natural disasters that we deal with here. We have blizzards, we have tornados, we have flooding. We don't have earthquakes, or hurricanes, or tsunamis. So, of course, we talk about the weather. But now we're talking about bridges.

The I-35W bridge across the Mississippi is as complicated in its death  as it was simple during its life . For many of us, it is as though we lost a family member. Many of us drove that bridge twice a day; I myself drove it about twice a week. Its death has caused tangled emotions and tangled conversations, no less than it has caused tangled traffic. Some of us ran to give first aid help; some of us ran for our cameras; some of us ran away. Some of us want to get as close to it as possible; some of us can't even see pictures without shedding tears. Some of us blame the mayor; some blame the governor; some blame the legislature; some blame the construction company doing repairs. Some of us want to spend more on all of our highways; some of us want to spend more on mass transit; some of us want to spend more on maintaining the status quo.

I just want to buy a hammer .
