In SoCal, there is a local chain, Turners, that carries a nice fishing backpack. Comes with 4 3600 boxes that fit in the bottom (with a zippered opening on the back so you access them directly), a big open section on top that's bigger than a six pack and lots of side pockets. Since they aren't a national chain, I thought they just rebranded somebody else's backpack, but I haven't found anything like it on the web. A little on the heavy side, but it stands upright without any boxes in the bottom, so it's sturdy.
