Found a soft, light blue queen-sized comforter on the walking trail near Yakima Greenway.

I found a soft, light blue queen-sized comforter on the walking trail near Yakima Greenway last weekend. It was draped over a park bench, and I thought it might belong to someone who had been enjoying the area. It's in very good condition with no visible stains. If it's yours, please describe it to reclaim it.
