Big Bay Point Lighthouse, Big Bay, Michigan

Here on the north shore of Michigan's Upper Peninsula, William Prior, who became this station's inaugural keeper in 1896, finally may have given up his duties. Surveying Lake Superior from atop a 60-foot bluff, the light station now operates as a romantic bed-and-breakfast with fireplaces and even spa services. William, dead these past 105 years, apparently still insisted on "helping"―until innkeeper Linda Gamble angrily told him off when his slamming of kitchen cabinet doors awakened her one night a few years ago. Neither William nor the other five resident ghosts have been heard from since. Well, so far, anyway; 906/345-9957 or bigbaylighthouse.com.
