What low-cost community events have successfully brought diverse neighbors together?

[William.J]

I'm on the planning committee for our neighborhood association, and we're trying to revitalize our local community events after a few quiet years. Our annual street fair used to be well-attended, but lately it feels stale and draws the same small crowd. We have a modest budget and rely on volunteers, so we're brainstorming ideas for low-cost, inclusive events that could appeal to both young families and older residents. What types of gatherings—like potlucks, movie nights, or skill-sharing workshops—have successfully brought diverse groups together in your own neighborhoods?
