Lost rare vintage 1970s Rod Carew baseball card in a protective sleeve near a bench at Riverside Park in Grand Forks.

I recently lost a rare vintage baseball card from the 1970s, featuring Rod Carew, while out for a walk near the Riverside Park in Grand Forks. It's in a protective sleeve and has some sentimental value. I last remember seeing it when I stopped at a bench to tie my shoelaces. If anyone finds it, I would greatly appreciate getting it back!
