Aww what the heck. Civil War era. I wanna see what happend that divided the States and the events that led to my state to be formed. If not there, give me a video camera, I wanna film T-Rex in full action.
Well... First, I'd use the antiquated POS to help me track down a TARDIS. If I'm going to travel in time, might as well do it in style.
After this, I'd jump back exactly seven days before I found the DeLorean, leave cryptic, ominous messages for myself, sit back and watch past-me panic. Next, I'd find myself a companion, preferably a redhead, and aimlessly hop back and forth in time, seeing just how much I can fiddle with the timestream before I accidentally cause the sun to explode.
And this is why I shouldn't be trusted with any form of technology.
