Query: Maine, by Kathleen M. Brandes

This book has become an invaluable source! I've now travelled to Maine twice and brought the book both times. Brandes provides a wealth of information, especially for those things off the beaten path. The book includes very helpful maps - on my last trip I left my Maine atlas at home and found the maps included in the book to be quite helpful. The spine on my book is really starting to see some wear - I enjoy reading it even when I'm not travelling. I highly recommend this book, especially if you are planning to travel to the northern, less populated regions of Maine.
