After vacationing with my parents in Wisconsin, we took the scenic route home through the Upper Peninsula. We crossed the Mackinac Bridge and got a hotel room in Mackinaw City. (Incidentally, whether it's spelled "Mackinac" or Mackinaw," it's pronounced "Mackinaw.")
The Old Mackinac Point Lighthouse was in a park right across the street. It was advertised as a maritime museum, accessible on the admission ticket for Fort Michilimackinac. It was closed for renovation, but they forgot to lower the price of the admission ticket for the fort.
The lighthouse began as a foghorn station in 1890 and remained in operation until 1957 when the Mackinac Bridge (visible on the right in the top photo) opened.
Incidentally, the bridge is the dividing line between Lake Huron and Lake Michigan. Which caused me to wonder — Did they build the bridge on the exact line or has the man-made structure taken on geographic significance? And what is the record for most times an individual fish has crossed from one lake to the other?
