Practice.

Four and a half hours driving within a span of seven hours, 250 miles covered in a triangle over eastern Kansas, and I'm right back where I started, minus $35 in gas, my MacBook that is in for repairs ("Oh, we've heard about this from many other people. We'll just go ahead and take it in; you can pick it up next week."), and several minutes of my life spent lipsynching to 'Hips Don't Lie' by Shakira while stuck in traffic coming off I-35. If nothing else, it's preparing me for the full-day drive in a couple of weeks. That is, if my car doesn't melt before that.
