Rural Sonoma County. I love it. No, that's not a truck; it's the front end of a truck turned into a garden ornament. Snapped this shot on my morning walk on a recent misty morning. I love the mist. It reminds me of English countryside and makes for great Pinot Noir.

... so I refocused and zoomed (those terms seem archaic for a modern iPhone) to capture a wonderful Scene of Greens. What a spectrum! I pass it on before the Republicans ban beautiful scenes. (Just wait; the regular folk like it, so Republicans will want to ban it, together with democracy.)

I was captivated by the evening sky (over the Pacific Ocean 10 miles away from my Sonoma home), and took an iPhone pic before the moment passed. But as I did, I noticed something else. ... [to be continued]

The golden rule when dealing with a cover-up scandal: anything other than releasing everything will make the situation worse. Those of us who remember Watergate have seen this show play out. open.substack.com/pub/robertre...

Californian poppies will spring up with the flimsiest of opportunities; in this case, cracks in the concrete in a corner of our driveway where I unload and store garden materials

The Economist tracker. Seems the Republicans know their voters. These are our fellow citizens. They are in the minority, but their numbers are growing. Hard to know what to make of this.

Here's two from last May to whet your appetite. This is the small park across the street from our front door. I walk over the little bridge to get the tram to the uni each day. The guy on the pedestal is Hans Christian Anderson, local boy who made good.

I'm looking forward to spending May in Denmark, an advanced society that's an example to the world. My US friends envy my having such an opportunity. It will be my third visit as a Visiting Prof at SDU. As a native of Yorkshire, I may be descended from this guy, a short distance from my apartment.

Biden clearly screwed up with regard to having a finger on the pulse of the voters (as did pretty well all Democrats), but he did one hell of a job with running the country at a difficult time.

Trump is winning the propaganda war because he can fake being a smart man of action that fools half the voters and the GOP House and Senate supplicants. Good advice for patriots here: open.substack.com/pub/contrari...

Nothing unusual here. Just the present day #GOP behaving as we have come to expect. Why would you not want this clown as Attorney General? It's what a majority of electors voted for.

iPhone cameras are amazing. I took this early this morning to see if it could capture the low early morning sunlight and the mist. Other than using the tree for some shade, I just point-and-clicked (one handed with dog on leash in the other hand). Photo shows what I saw!

When we moved to the US in 1987, and were invited to Thanksgivings, we found they had no meaning to us. It lives on childhood memories. So we created our own tradition. Our annual Thanksgiving Dinner takes us back to life in early postwar Britain. (Fine wine from our own cellar is an addition!)

So my motel in Sunnyvale was is the middle of Silicon Valley corporate sprawl, with a major freeway interchange next door, and little chance to walk to a restaurant. The only no-drive option was a Turkish BBQ place sitting on the edge of the motel parking lot. 🙁 But I was hungry. What a gem!!!
