Can you visit Goethe Link Observatory? Yes
Indiana Astronomical Society holds public sessions and monthly meetings at the observatory's 36-inch telescope; see IAS events calendar.
A public night at an observatory usually starts at dusk with a short talk, then a line at the eyepiece of the main telescope for the Moon, a planet or a bright cluster, with volunteers' smaller telescopes set up outside. Dress for the night air even in summer: domes are not heated, so the telescope stays at outside temperature. Many nights sell out or cancel for clouds, so check the observatory's site on the day.
