All the other suggestions are excellent, but my aim is to get people to at least start with the bare minimum. If you keep adding all the excellent suggestions that come up you’ll wind up with my “minimal” survival pack that weighs 16 pounds and has hundreds of dollars worth of gear. Presenting that to the casual hiker is overwhelming. So I recommend the minimum that I’ve observed would result in a successful rescue. After that it’s increasing comfort, more terrain flexibility, better comms, and so forth.
And Daisy – if your question is to me, then yes.
