I’m VERY concerned about the Delta variant. There are rumors that the CDC is going to tighten its guidelines on fully vaccinated people.The US held SkAm and US Nationals because the state of Nevada let them. The same event plan would not have been allowed by any of the Canadian provincial governments, hence why SCI and Canadian Nationals did not happen.
The fed shouldn't (at least as things currently stand) have a problem hosting domestic competitions the way things are currently trending. The JGP was called off because international travel rules are still up in the air for the summer, and there's no way to guarantee that foreign skaters assigned to the junior event will be able to come.
