After touring the visitor's center and Exploratorium we stopped in to purchase a few gifts for family. We were disappointed that the Tshirts came in such limited sizes.. most geared towards small children. We did purchase quite a bit though and even found a couple of items for myself. :)

Great little souvenir shop. Many locally made products. And you know that the money you spend here goes to a good cause (Friends of the Horicon Marsh).
