Walk across the lake

At a family gathering, Fred's father, grandfather, and great-grandfather bragged that they had all been able to walk on water to the bar across the lake for their first legal drinks. So when Fred's 21st birthday came around, he rowed out to the center of the lake, stepped out of the boat, and nearly drowned. Fred climbed back in and went to see his grandmother.

"Grandma," he said, "it's my 21st birthday, so why can't I walk across the lake like my father, his father, and his father before him?"

Granny looked kindly into Fred's eyes and said, "Because they were all born in January, and you were born in August."

Mackinac Bridge

In 1958, the Mackinac Bridge, the world longest suspension bridge, was dedicated. Ceremonies began on 24 Jun with the first "Governor's Walk" across the bridge. (It had opened to traffic on 1 Nov 1957.) This bridge joins the upper and lower peninsulas of the state of Michigan, reducing the crossing time, from a couple of hours, to just 10 minutes. Ceremonial groundbreaking took place at the St. Ignace end of the bridge on 7 May 1954, and on the opposite shore at Mackinaw City the next day. Meanwhile caissons and superstructures were assembled as far away as Indiana, Pennsylvania and Ohio. Including approaches, the total length is 26,444-ft, needing 34 bridge support foundations. The main span is 3,800-ft long.
