Lost blue plush teddy bear with a red scarf at a park in the Poconos.

My son accidentally left his favorite blue teddy bear at the park during our family trip to the Poconos last weekend. It's a soft plush bear wearing a tiny red scarf, and it's been with him since he was a baby. We retraced our steps but couldn’t find it anywhere. If you see it, please let me know; it would mean the world to us!
