On weekday mornings, our walks occur under cover of darkness. I listen to my iPod as we make our way along the familiar, darkened route. On Saturday, however, we sleep in and begin our walk as the sun is rising. With the coming of spring the birds have returned, and they greet the dawn with song. On Saturdays I walk without iPod and rely on the cheeps and tweets, the chirps and the twitters, for my musical accompaniment. Their happy sounds make the morning a bit more glorious.
