Clovis and his mom, Dorcas, spent a weekend on bikes out at Cherry Creek State Park last fall, taking pictures and talking about transitions. Vague, yes, but that's what they say. Summer to fall, and so forth. They took rolls of photos on film (yes, Luddites, both) of leaves turning, flowers drying, seeds exploding: transitions. This is one, more may follow, depending on what else we've got to post. A nice photo, we say, though we're not sure who was on the trigger, mom or son.
