Yeah, when I was in St. Joe/Benton Harbor last weekend, I was surprised at how far the ice on the big lake appeared to extend. When I was a kid, we used to drive to Grand Haven or Muskegon State Parks and walk out on the ice. It's been a long time since that was possible. My grandpa also used to take us out on the frozen Grand Traverse Bay on a snowmobile-the east bay would freeze over from the OMP to Elk Rapids.
And, yes, they are now calling the Old Mission Penninsula the "OMP".
