@cicerone imposter,
Hello, c.i.
Osso directed me here, claiming it's a sort of sanctuary for Old Farts. I guess my word will suffice for a guest pass, without showing credentials to verify my qualifications.
Osso also mentioned that you were discussing Madrid's Plaza Mayor. I lived in Madrid for nearly three years in the late 60's, until mid-1970. I'm thinking you might like to view a pair of contrasting photos of the plaza. But irrespective of whether you do or not, here's the Plaza Mayor on any typical day, Monday thru Saturday.
And here's the plaza as it appears on a Sunday, the Rastro open-air market, commonly referred to as the flea market. Perhaps you took in the Rastro when you were there.
