masking on transit: better than I'd expected

I just made a carefully timed trip to Harvard Square, mostly to buy ice cream, and also to get dry-mouth spray at the CVS in Harvard Square. [I prefer the CVS/Bartell's generic to the Biotene it's a generic of, because the generic is less minty.]

Carefully timed: there were very few other passengers on the 73 bus, in either direction. I walked to the back and opened some of the bus windows, in addition to the ones that were already open.
