Assuming he is alive and you were him how long could you evade police trackers, dogs and aerial surveillance? It seems like tracking humans has become a lost art and anyone who can track an animal could hide their own tracks from a human. Dogs would be more difficult to evade but not impossible so long as you keep mobile. Aerial surveillance will pick up other people who aren't you and would be like looking for a needle in a hay stack.

How long would /out/ last?
