For those units interested in learning more about Gus Grissom there is a small, but nice, Gus Grissom Memorial located at Spring Mill State Park. Spring Mill is located right outside of Grissom's hometown of Mitchell, Indiana. The state park is also a great place for scouting units to visit even without the Memorial. It has a youth campground, hiking trails, caves, a cave boat tour, and a very nice pioneer village with interesting building to explore.
