Kona's new favorite indoor sport (apart from barking at anything that passes by his favorite window):
Sam stands at the bottom of our basement stairs; I stand at the top (or vice versa). She calls him
and he goes charging down the steps. I call him and he charges back up. Et cetera. This goes on until
he gets tired and flops on the floor in front of one of us. He loves it. It doesn't take much to amuse this pup.
