Where is Prophets Town SP? I was at Purdue from 1951 to 1954 and never heard it ever mentioned.
It’s just off I 65 at the north edge of West Lafayette along the west side of the Wabash River. It is Indiana’s newest state park, so it wasn’t around when you were at Purdue. if you google it, you can find its exact location; West Lafayette has grown a lot since you were there.
