Organized?
It's not.
I do however carry more than I will ever need...... or know how to use.
I have a lowepro Compuday pack, I have room for my body and four lenses... )Nikon D7000, 18-105AF-s, 50mm 1.8 AF, 28mm 2.8 AI, and 135mm 2.8 AI)... rocket bulb air blower thingy, assorted filters for all lenses (ND, CP, closeup and UV), SB-600 speedlight, radio trigger, battery charger, manuals, a slew of batteries, micro fiber cloth, a point and shoot with Hi-Speed video, a bottle of tums, a bottle of aspirin, 3 granola bars, a bottle of water....and the computer pouch nicely fits a 42" collapsable 5-in-1 reflector.
Best part is my bag just looks like a backpack, not a camera bag. I'm less likely to have to deal with thugs and other unsavory types. Not immune mind you, just less likely.
