Lake Huron is looking very ice free.
Ice free towards the Mackinac Bridge:
Ice free towards both lighthouses.
I called Arnold Line Ferry today to see if they had an estimated date of return. Not yet. Last year, ferries didn't run until April due to ice. I'll try again next week! (I want to teach Sunday School at our church on the mainland, and it's too expensive to fly every weekend).
What should you do when approaching a parked emergency vehicle with its lights flashing and you're on a bicycle? I don't know. But I rode on the sidewalk just in case. (Riding bikes on sidewalks is not legal on Mackinac Island, but I'm hoping it was okay in this situation.)
