Lost brown leather contact book with emergency numbers

I lost my brown leather contact book yesterday around 3pm near the Beaver Island State Park entrance on Grand Island Boulevard. It's a compact 4x3 inch notebook with a worn cover, a red bookmark ribbon, and a white sticker with the initials 'J.M.' on the inside front cover. Inside are handwritten emergency contacts and personal numbers from work and family; there's also a faint coffee stain on the back page. It has sentimental value—it's the only place I keep those numbers, and I really need it back so I can reach my sister and my doctor.
