I found a copy of a glossy travel guide this afternoon around 3:15 PM outside the Brown County Library on Walnut Street in Green Bay, near the main entrance's coffee cart. It's a softcover, about 9x6 inches, with a bright yellow cover and a cartoon lighthouse. Inside, there's a pencil note on page 72 that says 'For Mia' and a small doodle of a sailboat on the margin. The spine is creased and the pages show light dog-ears from someone who clearly enjoyed the read.
