Discovered it in Cap-Bon-Ami cache in Gaspesia, Quebec, Canada. As it was left in a cache placed by Park Canada (which forbids to live something in their caches) I just took it (saved it and saved geocaching in federal parks?) and left nothing in exchange. I could drop it in a Maritimes area cache (Prince-Edward-Island or Nova-Scotia) or bring it back in Montreal. Pick your choice, if I found another internet connexion during my trip, I will follow your desires.
