Query: GREAT BOOK!

Mr. Smith has produced an invaluable resource that will become a standard---I've had this book for a couple of years, but this year was the first I've had opportunity to put his words to practice. He's dead-on in his excellent advise, so this year's modest garden will definitely grow next year. I'm wearing out my copy from use---a book well-loved indeed! If your planning a vegetable garden and need help---look no further. HIGHLY RECOMMENDED!
