Here we find out what we're made of. First, it's what we eat. Second, it's what we love. Third, it's what we do. It's what we hear and touch and see. It's what we build, with our minds and with our hands. It's what we play and sing. It's what we want.
We're working to find a way of living, and living to find a way of working which can sustain us, our souls and bellies, our parents and children, and the land that is all which holds us. We shall be resourceful. We shall make due. We shall overcome. Just kidding. But we might kick ass. And we'll probably have to, in the years ahead. We're here to protect and serve that which is sacred and real, from the dirt in our toenails to the stars in our eyes. We're here for a short time, to see what we can learn.
The most important thing you could ever do is to choose a place and dig in. - Pete Seeger
