A lot of people.
Some folks are clearly afraid and fearful of COVID exposure outdoors. For example, I often see individuals making a point to avoid unmasked bikers or joggers on the Burke-Gilman trail...moving 5-10 feet off the trail and sometimes turning away. Occasionally it gets tense, as when one local scientist (not me) was angrily called a "Republican" when he was walking in a park without a mask.
The fear of outdoor spread even hit the management of Seattle Parks last year, when several parks and their parking lots were closed because of COVID fears.
