Cool cliffs. Alice used to go here with her dad growing up. If going with children, hold on to them. Alice's mom feared for their lives every time they would go.
Kind of far (~1.5 hr drive), but this is where William Henry Harrison is from. He was president for like a month--Indiana's pride and joy! In lieu of actually going here, you can watch Season 7 Episode 3 ("William Henry Harrison") of Parks and Recreation on Peacock™. Update: upon further research, Harrison was actually from Virginia and only moved to Indiana after John Adams appointed him the first Governor of the Indiana Territory in 1801.
If you venture over to Bloomington (~1 hour away, Alice's parents met there in grad school!), stop by and see the house that Curt Cignetti built with his bare hands.
