This is one of several caches that I have put out on Big Bradford Lake, which is a substantial flooding just south of Waters, Michigan. Geocachers can access this by kayak or canoe, or perhaps by a swim through fishy, weedy waters.
Big Bradford Lake is good for fishing, relaxing and wildlife viewing, with eagles, loons, kingfishers, ducks, turtles and muskrats among the bounty.
You will need to bring your own writing instrument.
