What to do if we get the fort

Well, this is unlikely but any plans for if we do.
I was thinking keeping the gatehouse up to Extremely heavy, except for twice a day or something, when it will go down to VS for entering survivors. The times will be spray on the gatehouse once organised, and some people will work the doors, smashing at the barricades, and then rebuilding them.

And the zombies left in, people take turns killing them.

It would never work someone would almost every hour destroy the cades to get in. But I also favor you other plan of just waiting a month then striking.
