My mask starts out over my chin, ready to pull up and over mouth & nose as conditions warrant. In earlier warm weather, the paved/shared trails were mobbed with walkers, so I switched to riding in the then blissfully emptier streets. Our mild winter has reduced foot traffic on trails a little, but you can still encounter lots of density of people on sunny, cold days... Unfortunately the car traffic has exploded back to, if not pre-Covid levels, something getting close. So those lovely roads from summer rides are no longer as attractive an option and the mask gets frequent use now, when back to navigating those shared trails.
