Keys on black leather keyring lost near Windmill Island Gardens

I lost my keys yesterday around 3pm near Windmill Island Gardens in Holland, MI. They're on a black leather keyring with two standard house keys and a car key. One key has a bright red plastic head, and there's a small round tag engraved 'JH' hanging from the ring. I was walking along Van Raalte Avenue by the Windmill Island parking lot, after grabbing a quick bite from a vendor near the docks. They unlock my apartment and my bike lock, so I'm really hoping they turn up soon. If found, email me at [email protected].
