What connected you to the Great Lakes: I grew up breathing the scent of big fresh water, listening to Great Lakes freighters salute one another in passage, and playing on shores from Oscoda to Paradise and Ipperwash to Naubinway. Now I am happiest when I'm paddling, whether it's on Lake Dubonnet, along the Huron River, or among the Apostle Islands.

Favorite place in Michigan: Esch Beach, in all seasons.

Fun fact: To mark certain sentimental milestones, our family has made a point of swimming together in all five Great Lakes in deliberate succession.

What connected you to the Great Lakes: Polling a home-made raft with my brothers up and down the shore of the East Arm of Grand Traverse Bay. I was fortunate that my parents moved their family—two girls, three boys—to Traverse City, by the time I was 5 years old we lived on the Bay, so, we grew up in and on the bay, felt its cold and warm temperatures, sensed its sweetwater smell, moods, its seasons and cycles, seches’ that flooded the beach, tore out docks, flipped over moored boats, ice skating, fishing, watersports, dressing up like pirates and pushing each other off row boats into the water.

Favorite place in Michigan: There are so many places that are “favorites,” it’s hard to say—Michigan’s beauty is soft, gentle, rough, rugged, and diverse from the ends of both peninsulas to the other ends. A few places-- Cathead Point, Lake Michigan’s Dunes, and vistas from the worn down mountains, cliffs and beaches that rim Marquette and Lake Superior.

Favorite Great Lakes fact: The distance from the border of southeastern Michigan to Ironwood and Michigan's border with Wisconsin in the Upper Peninsula is almost 650 miles--an 11-hour drive! Perhaps, longer than any distance within any state in the lower forty-eight! With lots of shoreline, rivers, lakes, creeks, wetlands, wildlife, pastures, farms, hills, and ridges, Great Lakes shoreline all the way.
