Waste of money.
I thought I was buying a thorough guide to the Corps campgrounds but it was nothing like what I expected. There are no accurate maps showing locations, just general outlines with a single dot representing a lake where campgrounds are. There are no maps of individual campgrounds with site numbers. Instead only a brief description is given like you might find in a simple camping directory. There is much more information on the internet but I wanted to buy a book to save all that time researching and printing. Now I'm out my money and still have to do it. This book isn't worth taking with me, that is unless I use it to start a fire. Very disappointed.
