I like your choices and your explanation for them but I feel like the go bag is cheating a bit for this scenario haha. Its like the Genie in a bottle scenario where you just wish for more wishes lol. If choosing an item that contains more items is allowed for your challenge then I want to change my tarp item into a pick up truck with a camper on it stocked with enough food to last me 3 months, survival gear, books and batteries and all the luxuries of home.

I know this is all for fun, I'm just giving you a hard time haha - but an item that contains many items kind of defeats the purpose of wracking your brain to try and decide what 3 essential items are most important to you. But again, I'm just giving you a hard time Lol
