Well, since you ask me where I would go, and not how logical or illogical the concept of time travel is I would go back to my childhood. I miss when Santa Clause existed, being able to play with my Barbies for hours and hours, when all homework was was coloring pictures rather than algebra, and when I didn't have horrible sleeping patterns. I also miss not having to worry about getting a job, learning how to drive a stick-shift, finding a way finish school or getting my GED.
