Lost leopard gecko near Canal Park in Duluth

I lost my leopard gecko, Niko. He's about 6 inches long, tan with dark brown speckles and a darker stripe down his back; his tail ends in a pale tip, and there's a tiny white dot under his left front toe pad. I last saw him yesterday around 4pm near Canal Park in Duluth, specifically the Lakewalk near the Aerial Lift Bridge, and he may be hiding in cracks between rocks or under shrubs by the fishing pier. This little guy means a lot to me and my family—he has sentimental value—and I really need him back.
