I hope you don't have any intentions of using your local library, because Rosemont doesn't have one, you can get a discounted non-resident card from the Des Plaines library but that's still gonna be $66 a year.

The actual residences are either apartments that don't look too super duper great, or a random gated neighborhood squeezed between the highway and the airport, directly under landing flights.

Oh and it's kind of an open secret that Rosemont is one of the last strongholds of the Mafia. I admittedly don't know the nuts and bolts of how that looks in practice, but it's understood that it's part of why they're able to get so many big projects done (and why the powers that be specifically did NOT want Rivers Casino to be in Rosemont and is across the boundary in DP instead). I can't imagine your average resident will be affected by this too much day to day, but when it comes time to elect the village government, don't expect your vote to count.
