The complicated backpack

So yesterday I started packing - a job I dread these days. For some reason, I string it out and annoy myself. I used to love packing and got it all done and dusted well in advance of my departure date. Anyhoo, I decided it was time to get acquainted with my backpack using the above booklet. After walking myself through the multiple compartments, I started to fill them. I think I have it sussed. One of my good friends suggested I draw myself a key so I can remember where everything is. She also said she hoped I wouldn't need a bag search because it would take Security some time to go through the whole pack.
