a place to stash the net that holds parcels to the floor? At least thats what i used it for before getting my NLA parcel tray thing, it doesn't really leave room for anything in there now.
I keep a printed copy of a classroom "script" that I use for my driving clinics. They don't get bent or crinkled, and so long as I remember they're there, I always have them. It's just remembering that you put something in it that's hard.
