Living in a city with other people can be tiresome

I think i need time off from the big city and maybe go camping , maybe with a friend, and to get away from civilization, I wonder how far can I get from civilization, and when i say camping i dont mean camping sites... cause .. oh man.. those are ugly.. i prefer puting my tent on some place in the mountain away from people... maybe one day when i get too dam sick of the people ... i will do that... I hope its safe and i dont get killed by some random guy... lol
