Lost lightweight blue windbreaker jacket with a small tear on the left sleeve and initials 'J.S.' inside, lost near Riverside Park, Grand Rapids.

I lost my lightweight blue windbreaker jacket while biking around Grand Rapids last Sunday. I think it might have fallen off after I stopped in Riverside Park for a break. It has a small tear on the left sleeve and my initials 'J.S.' written in black ink on the inside label.
