Nah not that other tourist trap...Bois Blanc Island!
If you know, you know about this slice of heaven in the straits! If it's new to you, do some research before you take a ride on Plaunts ferry! It's not for everyone!
*Upgraded the difficulty rating on this because it seems to stump newbies. If at first, you can't find it come back later and try again! Please do not post revealing hints in the log comments. Those types of logs will be deleted. It is rated difficut so fellow geocacher have been warned!
