You’re Stranded on a Desert Island (not dessert)
But that’s 5 things. Which are you dropping?
I apologize for being unclear.
I dropped the fishing pole. Mirror and knife cover it. Break the mirror and you have shiny lures, you can still start a fire with at and signal with a bunch of mirrors
I have two ones depending on the island.
There is some debate in this hypothetical as to which kind of island it is. Regardless of island type, fresh water is the #1 concern.
Pump for drinking on island without fresh water. But if I don't have to worry about making fresh water, I can dig a hole, fill the tarp with water put it in the hole and done
