You're looking for something unique and somewhat out of place. As such, it's recommended that cachers just go with the flow here, but a writing implement is required.
The Bracebridge Resource Management Centre (BRMC) is a great area to take a long or short hike depending on your mood. This cache is located very close to the BRMC entrance and can be considered of the Park & Grab variety.
Parking is available just inside the entrance.
