Ahjno,
You clearly lack the ability to read and interpret the obvious fact that my statement referred to canoeists and kayakers whom, in an emergency, may not be able to grab and retain their grab bag.
Canoeists and kayakers tend to secure their kit, not in backpacks on their backs, but in barrels, dry bags, plastic tubs and expensive waterproof cases (and lots of bin bags).
Almost without exception, ALL of their kit will be secured to their craft to ensure that it does not become lost through drifting out of reach, sinking or both, in an emergency.
Hence the use of a grab bag, IF it can be grabbed and retained, if not, .....well, that's where my last point hits home.
Rather than conduct a poll amongst your quoted 8.756 members, you may care to research actual instances in which experienced, motivated, well equipped outdoors travellers became separated from their fully equipped backpacks and had to rely on just what they carried on their person, in non warfare or theft scenario's.
Instances of this type have occurred in built up areas in western countries as well as more remote locations.
Thankfully, you have fully equipped yourself with your self made up survival tin, which you 'sometimes' carry with you 'in the woods for fun'.
No doubt Doug Ritter could learn a lot from you!
