I've added some events for the upcoming winter season in Washington,
Utah, Montana, Alberta and Manitoba to my biathlon event calendar...

... This list is likely incomplete, and may have inaccuracies. Things
change, etc, but hopefully it's useful to people wanting to find
events to attend.

I will post East Coast events as I find out about them, but as of now
haven't heard/seen anything.
