Mr. Daybeers, your immediate is noted.
What it does prompt, however, is the realization that even though COVID has hardly gone away, the attitude of "We The People of the World" towards such has significantly changed.
What Mr. Palmland noted during the height of the pandemic seems to be much less the case today, I think there is realization that the virus is endemic and that "We The People" should accept that and "just live with it".
Anyone in North America and Western Europe who chooses to lessen the severity of a possible infection has now done so by VAX. Annual "Boosters" will attempt to identify the viral strains expected to be active and tailor such to address them just as does the annual flu shot.
Now the last major mask mandate - air travelers arriving from Overseas - has come down; travel by any means within the USA has been "normalized".
In short, just like the airlines, Amtrak will become "fill 'em up".
