Today’s Desert Walk

I took today off from work, but am carless while my wife’s van is in the shop, so I took a little photo walk in the Sonoran Desert behind my house. I managed to capture a few shots of those elusive gnatcatchers, which are everywhere, but hate to have their picture taken.

Autumn in Cambridge, Massachusetts

I attended a scientific conference this week in Watertown, MA, a few miles from the Harvard Square, where I stayed.  The weather was spectacular—unusually warm for November, especially a week after the freak Halloween snowstorm.  The fall colors were beautiful, making me nostalgic for my younger years in Pennsylvania.
