John McPhee is just great at making every topic interesting. This book talks about the history of oranges and what the industry (particularly in Florida) was up to in 1975 - at the time, concentrated orange juice was just starting to take over from fresh-squeezed. I'd be very interested in learning how things have evolved in the last 50 years.

After finishing this book, I went to my local fancy grocery place and bought one of every orange and tangerine they had. A+, would do again.
