The 2nd confirmed cow detection was 5.6 miles from the 1st, still inside the quarantine zone. The quarantine zone has increased slightly but it doesn't appear to be expanded by 5.6 miles yet.

Trump's #NWScrewworm #quarantine map. I'm not seeing any clear 5.6 mile expansion of the supposed 12.6 mile radius quarantine zone around a 2nd detection as Trump's own NWS playbook calls for. So far the zones appear to follow property line maps as you can see by the jagged edges & are more rectangular than a true radius. Quarantine squares won't work very well on flys.
