There was an enormous dragonfly flitting around near the lake and I happened to have my camera with me.  It would not, however, cooperate.  I sat and waited for a good ten minutes, watching it zip past me over and over again, my camera held ready.

It never did stop.

But this one did.  A pretty little red dragonfly rested on the rock near my feet, so I captured this one instead.  Patience paid off in the end.
