The community in the prison has grown significantly and they are slowly becoming self sufficient. They are growing vegetables and raising pigs and soon will no longer need to go on food runs. For now, that's still a requirement and Glenn, Tyreese, Daryl, Michonne and several others go to a nearby army base to see what they can find. All goes well until a minor accident results in walkers dropping in on them. Back at the prison, Rick goes to check their trap line and comes across a woman who says she and her husband haven't eaten for four days and would like to join their camp. Rick is wary and, as it turns out, with good reason.

Six weeks before shooting began, fruits and vegetables were planted to turn the prison yard into a farmyard. The work was nearly ruined when a herd of deer got in and fed on the crops. See more
The group seems oblivious that they need build better living conditions and defenses, even after all they've been through and seeing the accomplishments of others. Although Atlanta is nearby and perfect neighborhoods surround them, next to nothing has been gathered or built. Even the guard towers (that had already been climbed once by an enemy sniper) are still not being properly used.
Rick had seen walkers smart enough to turn doorknobs, use rocks as tools, and be agile enough to climb high fences. Despite having 30 days, the prison still hasn't even been fortified from such thinking or skilled walkers.
In addition, Rick and his people had seen how easily The Governor/Woodbury and Morgan had dealt with walkers by building walls and/or traps. Despite Rick's group having materials all over and weeks to do the same, walkers are allowed to gather at the prison fence and watch them. See more

You didn't wake me up.
'Cause I knew you were up all night reading comics with a flashlight.
