Good start! Welcome to INGO!
Now go out for a weekend and live off of it(if u have less than a days walk to home, then ignore me)
Thats the only way to reallt know what else u need in your bag.
I would add more water and I would add some meat in some form to your GHK. I hope you never have to use this Kit. But I am glad you are thinking. Your survival depends on the quality of your brain. Be sure to thank God if you have a good Brain for surviving most everything. If you do not thank Him, you may not make it home. Remember, there is always luck.
Us here in Indy are depending on Luck. Know what I mean, jelly bean?
