Blue LEGO City set with minifigures

I lost my blue LEGO City set with minifigures yesterday around 3pm near the Bean in Millennium Park, Chicago. It's a medium-sized blue box, the lid has a small orange crab sticker, and inside are two minifigures—a firefighter and a lifeguard—plus a tiny red fire truck. The box is a bit dented on the top-left corner. It was a gift from my grandmother and has sentimental value for my kids, so I’d really appreciate getting it back. If you found it, shoot me a note at [email protected] and we can figure out a meetup near the Bean or the south entrance of Millennium Park.
