I would still plant something edible Assuming it grows there of course. Some fruit trees would be nice.
If you grow it, you have to take care of it. I grew up in dairy country and we had a one acre garden for the family when I was a kid. We pretty much grew all the vegetables we ate. I remember it being a lot of work to keep up with and my mom didn't work. These days things are quite different. My garden is still pretty big, but not so big it takes up all our spare time (gotta brew, bro!). You can't beat fresh, for sure. I guess you could grow something less labor intensive, like barley or wheat, but it's still a b**** to plant and harvest if you have a crapload and you don't have the right equipment.
I really appreciate the hard work that farmers do, having helped when I was a kid. That's probably why I am an engineer now (farming is way too hard
). Of course, this is kind of off subject for this thread.
