I got really excited when first reading this book, about the prospects of greenhouse growing in Michigan during the winter. That is until someone reminded me how cloudy MI is during the winter...so I did some research, and sure enough, the part of Maine the author lives in has more sunny days than the US average in winter, whereas Michigan is among the cloudiest of all areas, with sunny days far below the national average. It's still a good book, but I think the author should've made as much a point of cloud cover as he did latitude.
