If there are squirrels all over DC, shouldn't sensors pick up on it more frequently? I think the Hippies tracked it in.
I leave roadkill for the city crew to deal with. That's what taxes are for : )
True, but they are deploying the new very sensitive PCR devices and it hasn't rained in DC for more than a month (a lot of dust becoming airborne). I haven't seen how many samples were positive, but if it were a deliberate release it should be very high levels in many samples.
