Blue hardcover travel guide with yellow Post-it note

I lost my blue hardcover travel guide to Michigan's state parks yesterday around 3pm near the CMU Bookstore on University Avenue in Mount Pleasant, Central Michigan. The cover shows some edge wear. Inside, I left a hand-drawn map of a few favorite Michigan campsites and a bright yellow Post-it with my initials 'RP' on the first page. The book has sentimental value—my aunt gave it to me last year for weekend backpacking trips, and I really need it back for an upcoming trip. If anyone found it, please drop me a message; I’d be forever grateful.
