Great tips and I cant think of much to add except this. Never trust anything that requires batteries and plan to spend the night. These two rules aren’t as important as they were before cell phones and LED flashlights but if you spend enough time in the woods you will learn these two the hard way sooner or later. At the very least when I go in the woods I have a little pouch that goes on my belt with a multi tool, flash light wrapped in duct tape, steel match, 2 iodine tabs, 2 extra strength Tylenol, 2 bug repellant pads and a plastic whistle with a compass.
As far as my tip, buy a roll of camo duct tape and wrap your water bottle with some. You will be surprised just how often that it comes in handy.
