Again, great advice. At 16, I camped every other weekend with my friend. Sixteen years later we did the Great Smokey National Park portion of the Appalachian Trail together. Even with twice your age and experience, we still learned from our mistakes.

Like Cannibal said, if you have to ask, this is probably not a good idea. But, what would your parents agree to? I'd plan enough that my parents would be comfortable with a 3-day trip. Make sure that you can bail out easily.
