Welcome back, Gentle Reader(s), to my ongoing offerings of plague-themed playlists, scientifically attuned to the anxious tenor of the times (and if you've ever spent time with any anxious tenors, you know what I mean).   As of this writing we ('we' being those of us lucky enough to be quarantined in the Land of Entrapment) have been in Lockdown since approximately mid-March—over a month and a half of social distancing, carry-out dining and grocery store corona-dancing and dodging. Out on the byways of the City Indifferent most folks are being pretty assiduous regarding distancing, although encounters on the narrow sidewalks of the east side typically require one party (most often Your Humble Narrator) to step out into the not-so-tender mercies of the carriageway to allow for the prescribed six-foot exclusion zone. Face masks are not presently required for outdoor activities but I'd estimate that at least 50% of those on the streets are employing them. In the stores it's more like 75% or 80%. When heading out for my daily constitutional I typically carry a mask (just in case) as well as a precious small bottle of hand sanitizer should it happen that I come into manual contact with anything other than my own personage and possessions. Otherwise, spring is springing in all of its characteristic blustery glory and the diminished vehicular traffic seems to have rendered the typically untainted Santa Fe air even more pristine.
