Jake watched Kristie head up to the second floor and then turned back to Marcus and Dinah.  "I agree with Christie that our two biggest weaknesses at this point are the front glass door, and the sliding glass door to the outdoor gardening section.  All the other doors are either well protected or only open in like the fire doors.  If we completely block off these two big glass ones with lumber, that should stop their main points of attack but still allow us to escape through any of the fire doors."<br/><br/>Jake laid his M4 on the ground next to the checkout and his ruck sack.  He drew his pistol and checked to make sure he had a good amount of ammo.  "We really need to get these doors sealed off before it gets too dark.  I'll go grab some lumber, probably some big 2x4's or 4x4's and thick plywood," he pauses a second to drag up a large flatbed cart.  "We'll also need long decking screws, nails, hammers, and some battery powered drills.  Can one of you two pick up the fasteners and tools, while the other guards the door?"  He is about to trot off to the lumber section when he sees something on the shelf next to the checkout.  He grabs three red boxes and opens them revealing small air horns.  "I want each one of you to carry one of these.  There is a safety on the top to make sure you don't accidentally set it off, but if you see a ghoul inside the building or about to get inside, give it a blast.  I don't think it is wise for any one of us to try to take on one of them on our own."<br/><br/>"And one last thing," Jake mentioned before taking off, "if you see movement, remember there are a lot of birds that got in here, so don't start shooting right away."  With that, he wheeled the heavy cart round and started pushing it for the lumber section; its small wheels squeaking as it moved.
