I was curious what people were actually doing, so while Anna was playing in the "woods" along the edge of the bike path, I gathered some statistics. As each person passed along the path, I tracked mode of transportation (walk, run, bike, scooter/skateboard), apparent gender (female, male, child, unclear), and face covering status (covered, mouth only, removed, absent). Raw data is here.
In forty minutes on June 28th, from 9:41am to 10:21am I saw 179 people pass. Of these, 73% (131) were masked, 5% (9) had their nose exposed, 15% (27) had masks on their chin or otherwise removed, and 7% (12) had no mask at all:
With a person passing every 13 seconds, the path was a pretty crowded place. I only very rarely saw people putting on their masks, however, when coming close to others. For the analysis below I want to talk about people as being masked or not, and people with masks removed wouldn't qualify. Masks worn mouth-only are less clear, but since a large fraction of transmission seems to be via talking and coughing, I decided to count someone as masked if their mouth was covered, even if their nose was sticking out.
When looking at people by transportation, walkers (74%, 62/84) were a bit less likely to be masked than others (82%, 78/95), but not by much:
Looking by gender/age, women were less likely to be masked (72%, 56/78) than men (85%, 74/87).  Children were in between (77%, 10/13), though I didn't count children in bicycle trailers or strollers:
I'm curious what numbers look like in other areas. Talking impressions with friends, it sounds like this is a higher fraction of people wearing masks than in most places?
 I categorized people by apparent gender, and one person didn't read immediately as male or female.
