A couple years ago I received Patricia Schultz's 1,000 PLACES TO SEE BEFORE YOU DIE as a gift. I've enjoyed reading it, as well as checking off the places I've seen in the book's margins.
I just learned that a few weeks ago Schultz published a new book, 1000 PLACES TO SEE IN THE USA AND CANADA BEFORE YOU DIE.
Since I hope to eventually visit all 50 states and all the provinces of Canada, this book is a "must buy" for me. I expect it will be both a good read and a useful tool to help plan future trips.
