I feel obligated to update my bag post by adding this new Crumpler camera bag. We're planning a trip to Ireland and I needed the travel bag that will get me through that adventure with my camera. The perfect bag needs to be big enough to carry all your stuff, but without a lot of excess space and weight. In other words it has to pass the Goldilocks test...it has to be "just right."
This reminds me of a guide we once used on a wilderness canoe trip. While the rest of us on the trip carried quite a bit of expensive "outdoors" gear, our guide used the most basic and simple supplies imaginable. His water bottle was an old milk jug. He forgot his spoon, so he carved one out of a stick on the first night. He brought what was necessary, but not much else.
At what point did we move past "necessary" and enter the "excess" zone?
