I wish I had realized while in the city how much food I could grow without having land - rabbits, quails, potted goodies.
My family and I have a ton of stories, but the main one is that we didn't know anything about growing our own food 3 years ago and now we have a dairy cow, goats, chickens, rabbits, ducks and geese. So - meat, eggs, milk, herbs , the occasional tomato plus lots of fruit coming in the next few years (trees and berry bushes). It's very satisfying.
There are lots of us on here! Look for #homestead #permaculture
