Ok, Hat Island to Chicago is like 352 miles That was Hat Island, MI. I think we actually want Hat Island, WI. I realized that Green Bay and Gills Rock were about 180 degrees opposite each other on the sign post, so I measured the distance between them. Then I looked on that line for an area about 20 miles from Gills Rock. Once I zoomed in on that area, I searched for marina again, and found Egg Harbor Marina. It's Egg Harbor Marina.
