Query: Sketchy math, great read

I bought both of Alexander's books at the same time and read this one first. I had heard of it from a friend who retold to me the story of Alexander's expenditures and how they resulted in his cost of $64 for a tomato. While he does actually calculate out this expenditure, his math is flawed. He grew many other things in the garden including flowers, but yet he assigned them super/farmers market prices thus isolating the tomato as the full bearer of any uncovered costs. The same could be done for any crop in anyone's garden. He could have just as easily called it The $49 Cucumber.Aside from this one story which comes at the end of the book, the work on the whole is a must read for anyone considering taking on a large scale gardening project (particularly in the North Eastern US). He tackles the problems of insects, rots, molds, pests, deer, contractors, and ideals about organics.
