Every time I think that I’ve photographed the Parroquia San Miguel de Arcangel from every conceivable angle during the past five years, something new comes along.

It’s like in physics. Scientists were pretty sure that the Standard Model that addresses all “of nature’s known particles and forces” was The Overall Encompassing Answer to Everything.

Without getting technical and sounding very much like the lost chapter from “A Hitchhiker’s Guide to the Galaxy,” the answer is 2.

And then, along comes the tiny, quivering, muon, with its lifespan of two-millionths of a second.

Inserted into a circular racetrack of whirling particles, 40-billion muons came up with a different answer: 0.00233184110 (a one-tenth of 1 percent deviation from 2).

Well, that blows up a boatload of assumptions.

The lesson, I guess, is — when you think you know everything there is to know, know that there are muons creeping up behind you with a whole ‘nother idea that will mess you up.

You can read all about it here.

But, about the Parroquia. It is the most photographed icon in San Miguel de Allende, I do believe.

Like everybody else in this town with a cell phone, I can’t stop taking photos of it because … it is always looking different. The same, but different.

Our own quantitative interpretive paradigm.

Or just a very cool architectural icon that defines our city through the zillion photographs taken every day.

The photo above was taken from the rooftop Tunki by Handshake, a speakeasy in Centro, a part of the Casa de Sierra Nevada complex.

We were supposed to meet friends Steve and Sue Blair up there for a drink before heading out to dinner. But — Yikes! — where was it? We stood at the corner of Hospicio and Recreo looking for a sign — not from above, just a sign on a door.

Two young Sierra Nevada staffers walked by and they took us to the nearby Andanza restaurant where a hostess confirmed that our friends were indeed on the Tunki reservation list. (A slight consternation that we weren’t). She and another staffer cheerfully walked us around the corner to an unmarked door and up several flights of stairs to the mysterious Tunki.

Despite all the intrigue, it is a most-welcoming place where the accent is on Peruvian drinks and food and the view is as charming as any in San Miguel. Apparently, my friend Steve says, at the original Handshake in Mexico City, would-be customers get only 20 minutes before being cycled out for the next ones in the waiting line.

Much more relaxed and accommodating in San Miguel!

I had a couple of tasty Cusquena dark lagers while watching the sun slowly drop like a deflating balloon toward the horizon. Steve likes their light lager. Some of the gang enjoyed hand-crafted cocktails from an impressive list. (This isn’t a review. I’m just trying to recall our brief but enjoyable experience at Tunki. Heck yeah, we will return, soon as I figure out how … )

And I’ll bet the Parroquia looks quite different when we return — yet very much the same.
