I've read all of your comments and have decided to plan out the trip a bit more and wait until I finish high school. Also, I don't get why some of you are claiming that I said I will travel from LA to NY in a week. I never said it will take a week, I said I've been thinking all this week about taking this trip. It would at least take me 145 days to make the trip, and another 145 to get back from NY to LA, which is about 1 year.
Also for the 600 dollars, I think it is a great amount to take with me on this journey. I plan on sleeping in the streets and in the wild with my tent, and plan on using the money only to purchase food. And, if I ever to run short of funds, I can always rely on the hospitality of people during the journey.
Planning this trip is important, and you guys have cared enough to tell me this, but this I already know. I don't want to plan too much though because it takes the excitement of the journey out. I want to explore, and if lost, I want to find my own way out of the hole, I want to ask the locals around where I am, I want to engulf my mind into the journey, not thinking about anything else, but that.
