I took my dogs for a walk in a local park and saw there was a cross country running meet about to start. One school made their athletes wear face masks and the other didn't. The team without face masks led the race the whole way, both female and male teams, in spite of the mask team looking just as fit. Ranks up there as one of the dumbest things I've watched. Halfway through the course I saw the mask team had pulled down their masks so at least the nose was in view. But it didn't help.
