That's a good few choices you have with these! Having a book to pass the time is important, hopefully it's a really long one so you take a while to read it lol.
Like anything, if you get a gun with ammo you can figure it out. Cleaning them is a different story but not something that will be high on your priority list in a situation like that!
Bringing food is important for a situation like yours where you are stuck in the desert. That's definitely a tough one!
Ha yes, you understand perfectly.
Although I'm having a rethink about the books, lol.
What do I do when it gets dark?
