June 8. Automatic plant watering is like a rocket launch. You can try everything from the amount of water to the tightness of the hoses beforehand, but then you’re not there and the system has to do its job unattended, and then when a hose connector pops off or the power goes out and the interval memory is lost, the plants are badly off. I’m thinking of buying a webcam and remote irrigation next time after all. Of course, this could also fail, but then I would at least be able to watch it fail.

We fly a thousand miles in three hours with a three hour delay. That seems insignificant. We won’t remember it later. If we were to make the journey on foot in a hundred days, how many days would we spend differently than planned?
