what this hub covers
This hub covers Paris and the whole Île-de-France — all eight départements, so an event at Station F, on the Paris-Saclay plateau, in La Défense, Versailles, Saint-Denis, Créteil, Cergy or Marne-la-Vallée is listed here rather than under its own commune. It reaches past the region too, to the towns inside the commuter and TGV belt that are closer to Paris than to any other hub: Reims, Troyes and Châlons in the Grand Est, Rouen and Évreux in Normandy, Orléans and Chartres in the Centre-Val de Loire.

11 cities are deliberately folded into no hub at all — an event in Nice, Rennes, Brest, Caen, Le Havre, Tours, Bourges, Dijon, Besançon, Ajaccio or Bastia keeps its own city name and shows under all browse events.
