Cindy and I spent the next day driving, catching the ferry, and hiking Madeline Island.  Madeline Island is part of the Apostle Islands (although not in the National Lakeshore).  It is the biggest island (of 22) and has regular ferry service (car, bicycle, passenger, etc.).  It has a rocky part, like most of the Lake Superior shoreline and it has a sand beach part.  Both are shown in the pictures below:
