All depends on what you have. Got all those suburbs with wonderful grass to cut. I talked my parents into buying sacks of potatoes from a gardener, it was the only thing we were growing on the plot of land. Otherwise it was all coming out of their back yard. Half my back yard was dug up, this house I only have a quarter of the yard soil, I have been too much in pain to do much in the way of growing after working all day. Life is better now, retired, got weed for pain, will be doing some growing for sure.
Any place that you see needs a lawn mower could be used for growing. Even raised gardens. The problem is you have to take care of it, most would rather sit on the couch and watch football. I look at life in terms of when I grew up, how much we consumed. My parents went on a once in a lifetime trip back to Europe, we think we have to fly away every summer/winter to get away. I don't consume all that much, doesn't help the economy much though. Which I just hear Trump tanked. It might be best if he just went to his resort in Florida and just shut up.
