My compliments on an excellent choice, Jakers! And what a wonderful Fog Signal Building. We're well on our way to a fantastic Door County Series!

Cana Island
Sturgeon Bay
Eagle Bluff
Sherwood Point

I think Pottawatomie will make an excellent next choice. The two Bailey's Harbor Range lights would be cool too, or the North Pierhead Canal Station Lighthous, or how 'bout Plum Island lights, then there's Chambers Island, and the Old Bailey's Harbor birdcage light, and Pilot Island, then top 'em off with the Plum Island lifesaving station.
