Lost dark wood violin and black case with purple interior left at a rest area picnic area near Fargo.

I lost my beloved violin and its case while driving through North Dakota last weekend. I stopped at a rest area near Fargo, and when I got back on the road, I realized I left it behind in the picnic area. The violin has a beautiful dark wood finish, and the case is black with a purple interior. It has significant sentimental value to me, as it was a gift from my grandmother. If anyone has seen it, please contact me. I really miss it!
