Maybe we're thinking too small. Riding out the apololypse in the new Devon Tower might be the way to go. Might be fairly defensible and I bet those top floors are pretty swanky. Just my $.02.
Nah, the Crest in Edmond if it is a zombie outbreak. Just everyone bring some wood to board up the windows.
If the economy collapses then I plan to bunker in, at least for awhile.
