Not anymore! The government AOP/IRS anti-oil police will have him shut down by midnight. Too bad his secret was leaked.
For several years, my SIL bought one type of every variety of fruit tree that costco had. He planted them in large tubes. They never got much more than 6 feet tall, but were very busy and supplied more than enough fruit for a family of four (and relatives) could eat. He had around 70 (I know because I’d have to water them when they went on vacation). A few years back someone offered him $500 for one of his apple trees. He sold it. They’re going to be moving out of state, so he’s now sold all but three for several hundred each. I never asked him how much his water bill was.
