You won't need a boat for this one, even though the cache name might suggest you do. We bet very few people realized that there's a spot in SW MI where these two come together!
Two of us took several readings on our GPS devices to come up with the posted coordinates, so they should be pretty good at getting you to the right spot.
You're looking for a camo'd container, with a small token for the FTF, although the kids of the FTF cacher might enjoy the token a little more! ;-) So, give the token to the kids, and the "wiser" cachers in the party can go log the FTF!
This one is available in the winter, but could be more difficult depending on snow accumulations ... that's part of the fun with geocaching in Michigan winters, right?
