06:45 - All freeways are "green", i.e. free-flowing, except for a road closure on SR4 between Hercules and Martinez.
08:30 - All freeways are "green", except for some congestion in the immediate approaches to the toll plaza for the Bay Bridge (normal on a Saturday) and a little, brief, slowing at the I-680 - US 101 interchange in southeast San Jose.
My point in these ongoing posts is not that there are zero protests but whether they are large enough to affect traffic.
09:35 - All freeways are "green", except for some congestion in the immediate approaches to the toll plaza and entrance into SF for the Bay Bridge (normal on a Saturday) and miscellaneous brief slowdowns here and there in normal-pattern places.
Looking at my 2025 running events calendar, I see there are two significant events this morning, one in the east bay and one in the south bay, and a third Sunday at a two-day pumpkin festival in HalMoon Bay. The latter probably explains the slowdowns on SR1 just north and south of that city. Later I'll have a gander at the results for the two events running today.
12:10 - Traffic looks normal for a busy Saturday, which means it could be a less busy day to which Hate-Trump traffic might be added.

I just got back from doing ~3 1/4 miles, park-to-park, out-and-back, on the Los Gatos Creek Trail. It's usually fairly busy on a Saturday, and the park where I turn around is close to the Campbell civic plaza (library, city hall, main police station), a perfect place for one of the Hate-Trump events. That park was also the start/finish for one of the running events I mentioned above, though almost everyone had finished by the time I got there. So, what did I see/hear?
I saw and heard (Proggies love megaphones) nothing suggesting there was a Hate-Trump event. The only Hate-Trump paraphernalia I saw was one woman with a "Women's March" T-shirt, about 2 miles from the civic center. Probably just a lone vague suggestion of solidarity with Hate-Trumpers. Traffic on the trail was normal volume - runners, walkers, people walking dogs. So the volume of traffic on the trail was unaffected by the number of people attending Hate-Trump events.
What about the number of participants in the Campbell Oktoberfest 5K and 10K? There were 612 finishers between the two distances, plus event people, observing/cheering family and friends, and people working various booths for various schools, fitness gyms, and nutritional products. Slightly fewer finished the 2024 running of the event. The other event has a 30K distance, so there may be runners still on the course, and Internet connection may not be good at the start/finish area. Results from that event have not yet been posted online.
