Found with Coppertone, Kayla and Madden Maniac. We had ventured into the park looking to walk across the peninsula. Discovered that we could not do that without a short swim so we settled for a cache. After finding the cache and preparing to replace it we ran into the cache owners who were stopping by to check on its condition.
It took us a bit longer to find this one that we would have guessed. We must be falling out of practice.
