Far as I can tell, Rick has only been up and about for a week. It has been about two that he was left for dead.
The way the army was killing people in the hospital, would not trust them to be helpful.
Lay out tires, zombies just can't handle the tire drill, just have some spikes for them to fall on. Pits, like they can't find a bob cat tractor. But, I would have a personel carrier by now, also some portable generators, even some solar panels!
As I said, war hammer and shield would be my weapon, ponk!
Once I had a base of safety (see older post) I would be planning raids for supplies, four man team; a driver, a look out and two to enter and grab. I would be looking at homes, break in, hit the kitchen for can goods and get out. Also, be looking for food distribution centers for mother loads.
Oh, the Atlanta Aquarium...think I would check it out for some "mail" shark suits but then I know of other places in the Atanta area to find "armor".
