They drew a map on their website, must be legit ! (There is a grand total of one active club in my fully recognised Lacrosse country).

IOC and/or the host can chose whatever they want for whatever reasons (that they don't care to explain to anyone anyway, that's it if there is a reason to begin with).
Darts PDC world championship, hoping to catch some tennis if time zones permit. The occasional football games. And I make sure to watch any skeleton and bobsleigh events
