For the last 29 years, the faithful and the curious have braved the harsh Michigan winter on one Saturday in February or March to step onto the frozen surface of Little Traverse Bay, near Bayfront Park in Petoskey.There was a record crowd this year: According to the Emmet County Sheriff’s Department, 2,021 viewers made the hike on the frozen lake March 7. Sgt. Dennis Jessick of the Emmet County Sheriff’s Office Dive Team, who organizes the event each year, reported that many of the locals and international visitors stood in line for two and a half hours. They trudged single-file, 800 feet across the crystalline surface, headed toward two tents–one red and one black. Inside one tent a hole had been sawed through more than four feet of ice, allowing them to peer down into the frigid waters. There in the shade of the tent, it’s possible to see down to the sandy bottom of Lake Michigan.
