Lost medium brown leather jacket with silver zippers near Rowntree Park in York, PA.

I lost my favorite brown leather jacket while walking my dog near Rowntree Park in York. It's a medium size, with silver zippers and a soft, worn-out texture from years of use. It was a chilly evening around 5 PM on October 15th; I realized it was missing after we returned home. I would really love to get it back as it has sentimental value to me.
