"The sound of a gunshot ringing in their ears" #zombie

Coming up on the toll booth at the beginning of the causeway, neither man sees an attendant or anybody else for that matter.  Greg gets out cautiously.  He holds the gate open as Deacon pulls the truck through.  Closing the gate,

Greg returns to the truck, and comments on how eerie the drive is, “There just isn’t anybody around.” 

Deacon agrees.  They come to the marina where the road splits off in two different directions.  Deacon asks Greg which way to go as the truck comes to a stop.  

Greg looks at the map, his finger traces the road they were are on before directing Deacon, “Right!” 

Deacon turns right and drives a little further.  They fallow the road around a hill and catch a glimpse of the visitor center roughly one thousand yards away, nestled in the surrounding cliffs.  Deacon stops the truck and both of them get out with their rifles.  They use the rifle scopes to get a better view of the building, there is no sign of life anywhere.  It is a newer, modern building.  They make out at least two floors.   A large parking lot lies in front and wraps around the side of the building. 

“Look it even has solar panels on the roof,” Deacon exclaims, excited about the possibilities. 

They get back in the truck, and drive towards the visitor center.  All the while watching the building.  All of a sudden, one of the front tires is blown out, with the sound of a gunshot ringing in their ears.  The truck jerks to the right.  Deacon brings it to a stop and starts to cuss as they hurry to get out of the truck, and take cover behind the truck.  From a megaphone they here a voice instruct them to drop their weapons on the hood of the truck if they are friendly, or they will be shot.  Deacon stands up and un-holsters his pistol and sets it on the hood of his truck.  He looks at Greg and instructs him to stay there, and if anything happens to him he needs to go back and take care of everyone else.  Greg begins to argue.
