Lost maroon windbreaker with hood made of thin, water-resistant material near Riverside Park in Janesville.

I misplaced my maroon windbreaker while walking my dog around Riverside Park in Janesville yesterday afternoon. It has a hood and is made of thin, water-resistant material. I realized it was gone when I got home and I can't seem to recall where I might have dropped it. It's an old favorite of mine, so I'm really hoping someone finds it and returns it.
