So this is the gear for this trip, minus a few chargers that were being used during the photo session. The camera equipment weighs in at 30 pounds. The MacBook Pro with all of the paperwork, maps and support material weighs in at about 20 pounds. All of that is carry on.
So all of the camera gear goes into this pack which weighs 30 pounds. I could put the MacBook Pro in also, but in that space I carry a copy or two of my latest book to give out. Each copy weighs in at exactly 1 kilo (2.2 pounds).
