What connected you to the Great Lakes: Growing up camping on the shores of Lake Michigan. Every day the lake offered a different personality, sometimes calm, even placid, other days exerting its power. I learned to observe and listen to nature and the Lake was such a good teacher for that.
Favorite place in Michigan: Anywhere I can connect with our geologic history—hiking along the glacial moraines, on the beaches nestled under ancient dunes or along the crisp, clear waters of a spring-fed creek. So many special places to feel a connection.
Favorite Great Lakes fact: Only one percent of the water in the Great Lakes system is replenished each year. The rest is the legacy of glaciers. In other words, the Great Lakes are a finite resource that must be protected!

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.
