Blue reflective dog collar with bone tag

I lost my blue reflective dog collar yesterday around 6:15pm along Riverfront Parkway near the Walnut Street Bridge in downtown Chattanooga. It's a medium nylon collar, bright electric blue with a silver D-ring. The bone-shaped brass tag is engraved with 'Rex' and has a tiny paw print; there's a small fray on the inner edge from a rough sidewalk. It has sentimental value—Rex's safety tag and a gift from my sister—so I really need it back. My dog gets anxious without his collar, and the tag helps us with ID if he ever runs off. If you found it, please send me a note here; I can meet up around the Riverfront area or arrange pickup in Chattanooga.
