Gray travel neck pillow with blue trim

I lost my gray travel neck pillow yesterday around 3pm near the Main Street Square entrance in Rapid City, West SD. It's a memory-foam pillow with a soft, slightly pilled fabric cover, and it has a blue trim and a tiny red stitch on the left seam; there’s also a small black zipper pocket on the back. This thing is really sentimental to me—it was a gift from my sister before a big cross-country trip, and I really need it back. If you found it, please drop me a note and I’ll arrange to pick it up at the Main Street Square area or the nearby library.
