Look for book excerpts and sample images!
In the meantime, you will find a series of articles on the publisher site, https://www.civilwarcycling.com/blog/, whose purpose is to provide brief excerpts and sample maps and photographs from the guidebook. The first article is called "On great fields something stays," and it briefly describes the unique opportunity that the battlefield offers bicylists who want a visceral understanding of the meaning of the Battle of Gettysburg.
In great deeds something abides. On great fields something stays. Forms change and pass; bodies disappear, but spirits linger, to consecrate ground for the vision-place of souls. And reverent men and women from afar, and generations that know us not and that we know not of, heart-drawn to see where and by whom great things were suffered and done for them, shall come to this deathless field to ponder and dream; and lo! the shadow of a mighty presence shall wrap them in its bosom, and the power of the vision pass into their souls.
~ Col. Joshua Lawrence Chamberlain, 1889, at the dedication of the Maine monuments in Gettysburg, Pennsylvania
