Lost soft blue comforter with subtle floral pattern near Plattsburgh-Adirondacks, New York.

I lost my soft blue comforter while driving back from a trip to Plattsburgh-Adirondacks last weekend. I believe it may have flown out of my car during a stop at a rest area or along the route. It has a subtle floral pattern and is particularly dear to me as it was a gift from my grandmother.
