It's always a surprise to download photos from a digital camera, odd little reminders of where you were and what you saw and what you were thinking. That's the question this morning - what was I thinking? Over and over, the same photo - the big orange tractor up at the barn. Yes, it was hot. And yes, I was tired. But really, the tractor?

Anyway, here they are, two shots whose allure I can't explain: the tractor from afar, and the tractor wheel, close up.
