My first dive in the Great Lakes was 20 years ago. I remember descending into dark green water and limited visibility. My joke for years was, “Do you know why they call it Lake Erie? Because it’s just that—it’s Erie.” Soon after that, I moved to Florida with my family and forgot all about the Great Lakes because I had warm, tropical reefs in my backyard. Fast-forward to five years ago and I had my next experience diving in Lake Superior.
