in a zombie apocolypse,

Which fraternity/sorority would make the best fortress?

So I'm ruling out all low, street level houses since hills make for the greatest vantage points against impending hordes. That means Walnut Place Greek houses are at a disadvantage (AEPi, SAE, Theta, TriDelt, Alpha Phi, PhiDelt, ATO) where as the other side of the park is way more protected, especially Dke and DPhi.

I like Phi Psi's chances on Comstock. They have a hill. Their porches are great for protection. Plus they only have to worry about AGD as a warring faction next to them (although don't count out those girls too quick, their house seems sturdy and capable of withstanding the apocalyptic fallout).

TKE has too many open points of entrance and I see them falling fast while houses like kappa will rise to the occasion because of its fortress like appearance. AZD and Crow will probably band together because of their isolation from everyone else. Strength in numbers is always good during these times.

Thoughts?
