Canoedogs: I had a checklist that I picked up at Gander Mountain. I breezed through it (once), said "Yup, got things covered.", and promptly ended up in the situation.

Hikin_Jim: My AMK Thermo Lite bivvy was (is) in my closet at the house. It never made it into the backpack from the time I received it at Christmas.

What a dope!! At least it wasn't lethal or damaging.
