With each letterbox recently hidden in a new location, just waiting to be discovered, you’re sure to have fun exploring nature (and creating great memories while doing so).

Available from Easter to Thanksgiving, follow the clues (found here) to find the hidden letterbox and take in the sights and sounds of nature along the way. Once found, use the stamp inside to mark your PLAN Passport, and take one of the cards inside with you and send it back telling us all about your experience.

Starting this Easter Sunday, we hope to see you out on the preserves following the new clues for a new adventure with family and friends!
