This is a great idea for starting programs for teens at your local library. Having fun isn’t hard, when you’ve got a library card!
“Hey, can we run a regular D&D game in that perpetually empty study room if we’re quiet?”
Most librarians would love to let you. They can probably also use that as an opportunity to add D&D books to their purchase orders.
My wife is a volunteer for Paizo Organized Play (the group that runs Pathfinder Society and Starfinder Society campaigns). When we were trying to restart in-person games in our area after Covid, the public libraries were a great resource. You’ll need to reserve the space you want to use ahead of time, and you may be limited in how often you can reserve it (so it doesn’t get monopolized by any one group or individual), but treat the space with respect and they’ll be glad to have you.
