You can make out at least 4 more shambling zombies in the store moving towards you.  An old fat man, a female clerk missing her left arm, and two younger teenage men.<br/><br/>The sound you heard behind you was the moan of a zombie at the edge of the parking lot.  From here it looks like a nurse or doctor since it is wearing teal green scrubs and a bloody face mask.  Behind it are at least another 8 zombies slowly stumbling from the vicinity of the hospital.<br/><br/>There are several dozen cars in the parking lot in various states of disrepair.  A jacked up pickup near your position just started rocking.  You can see a large zombie with a mullet still buckled up inside trying to beat his way through the door.
