Mexico will see a very visible bi celebration this weekend to mark Bi Visibility Day. On Sunday 21 September an estimated 100 people will come together on the centre of a large roundabout in the road network of Tijuana – the second largest city in Mexico. Bring bi flags – it will be about waving many bi flags high in the air in an endeavour to be seen by a great many people passing. The Cuauhtémoc roundabout is more grandiose than its name might suggest – one of a series of traffic intersections that celebrate Mexican history. Cuauhtémoc roundabout is in Zona Urbana Rio Tijuana, 22010 Tijuana, B.C., Mexico.
