Rooting for underdogs!
I wouldn't worry about it. I'm sure the Junior events will turn up.
Junior events often don't show up in Peacock listing until a couple of days beforehand. I'd only be worried if they still aren't listed on Monday.I'm a little concerned about the Peacock coverage of 2022 U. S. Nationals. I checked the streaming coverage today and all of the Championship (Senior) events are listed but NONE of the Junior events are listed. The first Jr. event is on January 4 and the first Championship event is on January 6.
I sent an email to USFS asking about the Jr. coverage but haven't received a reply. I also spent 30 minutes trying to speak or chat over the internet with someone at Peacock but the "bot" never found an agent to answer my questions.
