For any Vonnegut fans who find themselves in Indianapolis, I recommend checking out the Kurt Vonnegut Museum and Library: https://www.vonnegutlibrary.org/

When I visited for the first time this year, I learned about GHQ and the upcoming release

The nearby city of Bloomington, home of Indiana University, also hosts Granfalloon each year. I believe it's in July? I just happened to be in town for work and caught it.

I also recommend it. I was in the city for Gen Con last year and decided to go and it was a very interesting museum.

Lots of letters and interesting artifacts and tidbits about his life.
