A) Nothing, just totally naked
B) What you’re wearing and anything you carry with you (even if you’re not carrying it right now) like a bag
C) What you’re wearing, what you carry with you, and the contents of your home (it will be teleported within a few hundred metres on the surface in an accessible location, but obviously won’t be connected to any services like electricity or water)
A) I’m very resourceful and have formal wilderness training, but naked and completely foreign environs… Probably not going to do so well, especially if the weather is harsh.
B) Pretty well. My backpack is my bag of tricks and my daily loadout includes my multitool, an IFAK, some clothing layers, and two water bottles. But it’s still going to be a challenge because of completely foreign environs.
C) Perfectly awesome, living my best life. My home is my sailboat with solar, 40000Wh battery storage, water makers, extensive first aid, dried food and spices, and more books, movies, and video games than I could possibly finish in my remaining years.
You win.
