City: Seattle
Neighborhood: Georgetown/Sodo
Building or Defensible Location: Costco warehouse

Attributes:
Concrete building with few windows, a huge parking area, flat roof. Since it sells food and other household supplies, seems like a good spot to hole up for a while. Also, has a gas station nearby for powering generators!

Pros:

• No windows
• Heavy metal doors can be sealed
• Rooftop may provide excellent concealment / cover for the .50 caliber defensive emplacements.
• stocked with:
  • Food (dry goods especially)
  • Water
  • Supplies
  • Portable Generators
  • Tools for fabrication
  • Full Kitchen
  • Fuel Station at most (you'll need to figure out how to get the fuel from the station to inside. Get some lackey surfer boi to do it)
• Able to add other survivors without exceptional drain on resources.
• Need to show membership card to gain entry.
  
• Probably very soundproof, which may help keep zombie attentions to a minimum.
• Plenty of blunt weapons, projectile weapons, and easily improvised to become a weapon items.
• Tire center can be used as a quarantine area. Newcomers can be set aside before adding to general population.
• Forklifts run on propane which is efficient and can be used to run other camping items in the store.
• They have a car wash, where a Draw Down™ would be inevitable.
  

Cons:

• Access to the store could damage the very defensible doors we would want to keep
• The legendary Costco hot dogs can produce some noxious gas.
  
• In an urban area, so higher potential of zombies flocking there
• Need to show membership card to gain entry.
• Lack of knowledge about how to manage the emergency systems - may need a Costco guide. Could probably find one at the store.
• If it all goes to hell, there aren't a lot of easy fall back locations.
• Costco does not sell / stock ammunition, firearms nor destructive devices, although they do usually have an abundance of chainsaws.
  
• During business hours there may be customers inside, you may meet resistance in trying to secure the area. Force may be necessary. Zombie infection may have already occurred in the store. You'll almost definitely need to be armed.
• Yuppie wines can be turned into Molotov Cocktails.

Entertainment:
As time passes, entertainment will be necessary to overcome cabin fever. Initially, watching DVDs and Playing Xbox would pass the time, but even that would get old. The following ideas come to mind.

• Forklift Jousting
• Assemble a set of racks in a square. Attach the leads of a generator to the racks. Lower the rack assembly down to the parking lot from the roof, have a lackey sit in the middle: Zombie bug-zapper
• Set up a trampoline on the roof. Using tires from the tire center; fill them with fuel, light, and bounce off of trampoline into hordes of Zombies.
• Watch lackey go get fuel in up armored forklift
• Build a fort in the racks
• They have a pharmacy, you figure it out.

In the case of an outbreak, will you be allowing other survivors to join you here? Yeah, if you're not an asshole or sporting any bite wounds. Bonus points for anybody arriving in an M35A2 Deuce-and-a-half loaded with enough arms and ammunition to equip a Ranger battalion.
