I think if I got to go anywhere in the world, I would try to visit a culture that is most unlike the one we all live in, one that doesn't rely on things like: computers, cars, cell phones, one almost completely untouched by technology.  As far as things I would bring, well, I'd want to bring as little as possible with me, not only to live the way the people of that culture would live it, but also to not disrupt the culture, to someone who doesn't know what a cell phone is, it could be seen as something evil.  So, what would I bring?  Although I might have expressed a strong dislike of the idea, I would bring a cell phone with me, for no other reason than to contact someone in case of an emergency.  In this thought I would also like to add on that I would bring medicine that might help in the case of an emergency.  Other then that the only thing I really need is clothing, used to keep me warm, as if you already didn't know that.

As far as what will sustain me while I'm there, I would rely on living as the people of the culture do and do what they do for there food, shelter, water, and other necessities of life.

Finally, I do think some of the things I like will be understandable, but I also think that more won't translate, things such as clothing, in a culture that is less advanced they might see clothing as not only a tool to keep their bodies warm but also to blend in with their surroundings during activities such as hunting, needless to say a bright red shirt would not work as effectively at this as it would in our use for clothing.
