we now have agreements with Canada to allow residents to make the trip to Blaine for necessary things - doctor's appointments, etc. Now that tRump is out of office and not hurling insults their way things seem to be going a little smoother.
The state has been providing a temporary foot ferry service a few days a week, when the water isn't too rough.
I haven't heard anything about how they're handling the school - the only school there only goes through 4th grade, and all older students took a bus through the two border crossings, each way, every day. Don't know if everything is still set up for distance learning.
Point Roberts is in a strange situation. In the mid-90's they discovered an animal with rabies there. The Americans couldn't bring their animals through the two border crossings to get them vaccinated in the mainland, and the US-approved vaccine was not approved for import into Canada. The Coast Guard set up some 'training missions' to get the vaccine and a veterinarian to the Point, and all the pets got their shots. A lot of Canadians own vacation homes there - like they showed in the video, they can't go across to tend their property.
