Red pocket travel guide with a green post-it note

I lost my red pocket travel guide yesterday around 3pm near the Castillo de San Marcos on King Street. It's a Lonely Planet Pocket Florida, about 4 by 7 inches, with a slightly bent spine and a coffee ring on the back cover. The inside has a bright green Post-it note stuck on page 12 with a quick itinerary, and the pages are dog-eared from frequent use. This book was a gift from my sister and means a lot to me—it's my go-to reference when I explore St Augustine, and I really need it back. If anyone found it, please get in touch; I can meet near the Old City Gate or the Plaza de la Constitución to pick it up.
