I'd imaging that alot of us have daypacks/backpacks for our photography equipment, but there are some things that you consider equipment that doesn't really fall under that heading (photograph related, but non-camera related.) i.e a light meter, small stuffed animals, guitar picks, general purpose dog treats, and a towel (never go anywhere without your towel
) are some of the things that I carry in my daypack aside from my cameras. So what do you carry in your daypack?
