You know, I have a lot of books on my iPad, but when I try to read them, I find myself wandering off to play games. Those are books I'm interested in. I can't imagine what would have happened to me in college if my biology class had been on the same computer as "Words With Friends" and "Doom."

I write about how in Midland, the mayor instituted water conservation measures like restrictions on car washing. He made a point though that they were only "suggestions" and not government telling people what to do. But then his constituents got very ticked off at the sight of their neighbors breaking the rules and demanded that they be made into actual laws with penalties.

I did some research once on the way people in the past imagined the year 2000. They tended to picture the things they already had getting more sophisticated - flying cars, self-cleaning windows. And the folks in the early 1900s had a wildly optimistic estimate of the future of pneumatic tubes.

You reduce illegal immigration by making it harder to get jobs here, or easier to get jobs south of the border. This idea that we can't pass an immigration law until we hit some imaginary security target is just a way to derail reform.

My only thought about Margaret Thatcher is the same one I had about Ronald Reagan. I hated a lot of what they did, but once in a while a country just needs a change.

For the undocumented immigrants, the big priority is just to get out from the shadows, be able to get a driver's license, buy an airplane ticket and stop worrying about sudden deportation. But for the country as a whole, it's crucial that everybody have a citizen's stake in the nation's welfare.
