@chargrille @inthehands Seasonality occurred to me too. Maybe some of these previously covid-cautious people just associate covid & illness w/ winter & cold weather, so beautiful, warm, sunny weather makes them throw off their masks.
Every time we've had a low/low-ish period in wastewater, I've kept our masks because there was always chatter about new variants on the horizon. I'm not hearing as much chatter now, but still waiting for sustained actual lows before even considering going maskless.
