Some quotes from this article.
"...lettuce is embarrassingly easy to grow. I grew some in a hanging basket last year. All it took was a squirt of vinaigrette, and I didn’t even have to bend over to eat it."
“Basically, it’s instant gratification stuff, going to the grocery store for basil when you can grow it in the back of your pickup truck.” Mr. Rushing is not speaking hypothetically. He planted a garden in the bed of his beat-up, brown-and-white Ford F150.
