I've seen that same thing! But I live about an hour away from Seattle, and I'm generally seeing way fewer people shake hands and several people I know (my family included) are avoiding unnecessary trips into public. I mostly just wonder where the threshold is between population density and social distancing and R0. Obviously total quarantine does wonders, and completely normal behavior is terrible, but is it enough if half the population takes precautions? Or 2/3 or 1/3? I've been thinking of it kind of like a graph or a web, and if you cut enough of the connections, the spread stops, and "enough" isn't anything like "all," and the more strategically placed the cuts are, the fewer there can be, but it's not easy to figure out exactly how many cuts you need.
