Tuesday, we found breakfast in Healdsburg at the Flakey Creamy Donut Shop. 
World's Largest
It is really more a café than donut shop, although the latter look tasty. We were there before sunup. Our fellow diners included a half-dozen men talking about the collecting of classic cars. Our plan was to make a short stop in Ukiah and then to drive along the Russian River to Bodega Bay.
It was, of course, another twisty, hilly, narrow road through miles and miles of vineyards, and gorgeous scenery. But then we began to find Construction is not just another word for Summer: road surfaces are being repaired throughout Mendocino and Sonoma counties. The first encounter was not far from Healdsburg where a hastily set up warning sign announced BRIDGE OUT ROAD CLOSED OCT 5. Of course, our Maps application on our cell phone hadn't been told so before we realized it, we had gone in a circle and started our second loop; the software really wanted us to cross that bridge!
We never quite recovered, because here again the Internet comes and goes. But we knew enough about the area, and we had plenty of paper maps, so we

managed nicely. At least a half dozen stops were due to planned road repaving, waiting for the flagger to let us pass.
Much more fun, and the high spot of the trip today, was a stop at the WORLD'S LARGEST REDWOOD GAS STATION in Ukiah. "The "World's Largest Redwood Tree Service Station" opened in 1936 when North State Street was Highway 101. The massive tree was over 1500 years old when it was carefully selected from a grove of monster redwoods 17 miles west of Ukiah."
The trunk is still there, and the office inside is still open, with plenty of old photos and license plates to please aficionados. We have a 72 MB video which we'll send through the cloud to any reader who requests it.
We reached Bodega Bay in time for a good seafood lunch while watching seabirds fly across the top of the water. Additional sights were an old church and a 19th-century schoolhouse, more recently lovingly restored by the family who bought it in the mid 1950s. The family still lives in it.
We were getting tired, and the traffic was too heavy for sightseeing, so we concluded our trip by returning to the hotel to prepare to return to the real world tomorrow, perhaps singing "Most Happy Fella."
