As I again return to the photo of the birch tree, my mind takes me in another direction, out over the shimmering waters, fading to the horizon. Upon close inspection of the photo, "to the horizon" reveals a structure reaching above the rich blues and greens; beyond the shimmering lights, flashing off the waves of Lake Michigan, yet still well within the expansive waters. And all conceived and constructed within a century's time ...that towering landmark, the Mackinaw Bridge. Considering the commitment, dedication, and sacrifice put into its construction, no doubt it was nicknamed the "Mighty Mac." Yet, so much is taken for granted, and most of the time little thought is associated with that sort of thing. Today, most would probably assume the "Mighty Mac" to be a new entree among a long list of McDonald's burgers.
