Around America in 80 Days

Every few Saturdays, Oaxaca's Teatro Macedonia Alcalá, projects a live (via satelite) performance of the New York Metropolitan Opera.  Heard in the splendor of the historic theater, the music is an exciting experience.   We became devout opera fans.  Even while travelling, we try to find the local Met transmissions.
Three years ago, we planned a coast-to-coast drive, aiming to sit in the Met for a real performance.  Life had a different idea, and we had to cancel.  The following year, Adi was weak from the effects of chemotherapy, and could not endure such a task.  A year later, still too weak to drive, we flew from Oaxaca to New York, and enjoyed a wonderful Aida.
This year, Adi challenged herself, 'Will I have the stamina for a transcontinental trip?'
We decided to go, with one condition in mind, 'If in doubt, we head back to Oaxaca.'
Back in California after visiting Korea and Israel, we liberated Dino out of storage, and set out on our adventure.
