Benzie County Ghost Towns Series #7 of 22
Benzie County had a plethora of small communities, especially during the early lumber boom. Each Cache in this Series is near where a Post Office use to operate.
I could not find any information about Grace other than the post office opened April 14, 1880 and closed August 19, 1884.
