Where Knowledge Creates Wisdom
Format: Paperback
A must-read for anyone seeking the title of King/Queen of Minutae. Weather predictions are typically, freakishly spot-on. There is simply a wealth of information in here that you are better off knowing, or will at least make you popular on trivia night. There are some quality vendors that you don't see online advertising in here too. The only drawbacks are the snowfall total in Florida challenging Central Oregon this winter, and the increase in price over last year. Tariffs on paper?

Good quality book.
Format: Paperback
Bought these because I bought one for my grandmother every year for Christmas. It is good quality, but I have only opened it one time. I got it for sentimental reasons.
