Haven't been in Indiana much myself.
Off the top of my head, I know I drove thru it on I-80 in like 1980 to go to Iowa City via Chicago. IIRC, it was a toll road with limited exits. The only place in Indiana we stopped for long was Notre Dame Univ which was smaller than I had imagined.
And, in 1985, while visiting a "sister" Computer Shoppe in Louisville, KY, I went to a colleagues home for dinner nearby in Indiana. I have no idea what town.
