In Indiana, it is illegal to ride public transportation and play chess.

The claim about Indiana prohibiting chess on public transportation is false. This appears to be a fictional 'dumb law' or urban legend of the type commonly circulated in trivia books and websites listing bizarre legislation. While many U.S. states have unusual or archaic laws on the books (often from earlier centuries), there's no documented evidence of such a law existing in Indiana's actual legal code. These types of fake laws often originate from satire, jokes, or misunderstandings and get repeated as 'facts' in pop culture.
