Anyone carry a backpack around all day?
How comfortable would it be to carry around a half full backpack all day? I'll be carrying around a camera on each shoulder all day and would like a) something to put them in should it rain (or if I want a break) and b) something to put other things in, e.g. water bottle, small blanket to sit on while watching the afternoon airshow, a third lens (large) and camera body (small) and any materials I might (okay...will) pick up throughout the day. I'm thinking about purchasing a North Face Surge bag since I'd rather not carry around my huge Lowepro camera bag that tells the world what's inside. Otherwise I don't see any other alternative to accomplishing what I want to accomplish.
