The white folks at the store where we got our supplies said that Indians made such good berry pickers because something sour in our blood kept the blackflies away. But even then, as a boy of six, I knew that wasn't true. Blackflies don't discriminate. But now, lying here almost fifty years to the day and getting eaten from the inside out by a disease I can't even see, I'm not sure what's true and what's not anymore. Maybe we are sour.
