When not composing on the computer (and before that on a Remington Quiet- Riter exactly like this one which my parents bought me as a junior high graduation gift), I jot down bits and pieces of rantings and ravings on a 7 1/8 x 5 1/4 inch account book--the perfect size for my miniscule scribblings.
Number one starts on January 11, 1975 in Seattle and finishes (with stopovers in London and Paris) in Greece in July 1976; the one I'm currently scribbling in is number twelve. That's not much of an output but what can you expect from a humming bird.
