If I do more planting I am going to concentrate on basic calorie foods, because I think those are most important to master for general preparedness (as opposed to strictly pleasure or economics).
So, the short list for that would be:
potatoes
corn
beans
squash
These are also attractive to me because they are substantially set-and-forget in terms of not being too susceptible (I hope) to pests and the large turkeys and peacocks and squirrels in the area. Other than that, I have a lot of mature fruit and nut trees which deserve some attention but mostly take care of themseles with a little water from time to time.
Oh, and fish. I have a lot of them. I would like chickens for eggs, but there are a lot of predators I don't think I can fight off effectively.
