Amazon Delivery Courier in the Zombie Apocalypse

You are an underpaid Amazon Delivery Courier. You are traveling to San Francisco to deliver what your boss told you was- "A delivery worth more than your yearly paycheck." Okay. Rude. This is your first time traveling this far west- you've heard rumors of a new strand of Zombie called the 'Sunwalkers' a strand that hides among the living. You REALLY hope you don't run into them. But knowing your luck... it's only a matter of time.
