Colorful Melissa & Doug wooden train set

Yesterday around 3pm I realized my kid's favorite train set was missing. I was on Cannery Row near the Monterey Bay Aquarium, walking the boardwalk by the souvenir shops when it vanished. It's a Melissa & Doug wooden train set with a red engine, blue passenger car, and yellow caboose on light brown tracks. The engine has a tiny chrome whistle and one track piece has a slightly bent end; the lid of the box is worn and still says 'First Train' on the top. It's sentimental to us—a gift from grandma—and since I'm listing this in the Children's Toys & Games category for Monterey Bay, I'd be incredibly grateful to get it back.
