Redwood City's 4th of July Parade attracts a lot of people, but it still has a small-town vibe. The crowd reflects the diversity of the city itself as well as the surrounding Bay Area: many colors, many languages, many American flags; Girl Scouts followed by Mexican folkloric dancers followed by synchronized Falun Gong-ers.
After the parade... classic cars lined Broadway. Congresswoman Speiers's gun regulation sit-down in front of the old Fox Theatre attracted a small crowd, but the macarena (!) was booming from the sound system directly across the street, it was hard to hear, and most folks seemed more in the mood for a taco and a Bud than politics.
A larger audience assembled to see Stanford and UC-Davis square off in a battle of the marching bands (I use both "marching" and "band" loosely here). I'm afraid the Aggies came in larger numbers and readier to play, although the Stanford tree gave it his all. Both sides were passing around plastic "water" bottles, containing some liquid that only helped the musicianship up to a point.
I thought the best politics of the day was implicit in that patriotic rainbow crowd... you shoulda seen it, Mr. Trump. Then again, I suspect your presence might have soured the festive mood.
