Paul McCartney offered a concert last two days. Now as this is being posted, another concert is being held at the Zocalo, Mexico’s main plaza. A free concert, with more than 90,000 souls. That is pretty crowded. I rather stay home, this time. This is the Zocalo. Behind the scenery is the Cathedral. Photographs taken from several newspapers.
