These recommendations make it seem like attending a show is an extremely high risk event. It's excellent advice; wear a tight fitting N95 mask the entire time and pretty much every where you go and don't eat or drink or smoke. However, there's as much a chance of that happening as there is successfully commanding fifteen thousand dogs to sit/stay for three hours. That being said, the risk (assuming it's as high as inferred) is imminent. The only assured practices from a Covid 19 safety standpoint would be to stay home if you're worried. I'll be at the shows breaking bread with my new friends.
