I have started a series of kayaking caches on Canadice Lake. Each cache will start with a different letter of the alphabet (I was inspired by Team Daisydog's series). You will need to access these caches by boat, as swimming is not allowed at Canadice Lake and you cannot reach the caches from the shore.
You are looking for a small camo'd pill bottle that is tethered to a branch. There is no room for a pen so be sure to bring your own.
Canadice Lake is one of my favorite places to kayak and I hope you enjoy this series.
