I just returned from a 7,250 mile road trip, following many of the routes in this book, specifically the Great Northern to the Pacific Coast Highway to the Oregon Trail. Jamie's book contained so many useful stopping places, although if I had stopped at all of them, this trip would have taken months rather than weeks. In using the book, you have to choose what works for you - and not everything is of interest. However, he did lead me to some wonderful places like Sullys Hill Nature Preserve in Devil's Lake, MT; the Buffalo Bill Historic Museum in Cody, WY; and the museum dedicated to lumbering in Grand Rapids, MN - all of which I might well have bypassed had it not been for Jamie's recomendations.
If you are planning a road trip this summer, either near or far, this book is a great resource. It is also great for the armchair traveller. But beware, it may get you out of your armchair and on the road. Buyer beware!
