Walking up the front steps to Casa del Garrett I hear the familiar sound of my shoes crunching over spent shells from one of my bird feeders.   Crunch, crunch, crunch…up the steps, then into the house.   Once inside, I start up the steps to the second floor.   I notice the crunching sound is still happening.   I take the steps a little slower and listen carefully.   Crunch, crunch, crunch…

The sound is coming from my right knee, which has been feeling a little stiff lately.   Oh Foo.
