I typically carry my checkbook in my (currently cheap, rapidly deteriorating) backpack. Does anyone else here carry their checkbook in their backpack? If so, do you carry your checks in an Organizer Pouch, and which kind do you prefer to use? I use a standard cheapie vinyl 6.25-by-3.25-inch checkbook. I was thinking that if I bought a new Tom Bihn backpack, it would be interesting to figure out where to carry the checkbook.
