why are there crowds at Cheltenham when other events are suspended .It doesnt make sense .?

Other events got suspended just a couple of days after the Cheltenham festival, it was in doubt right up until the first day on the Tuesday but Boris Johnson let it take place before cancelling other sports events with big crowds on the weekend after Cheltenham 

You might say the same for Crufts which went ahead - the KC asked exhibitors from Italy not to come (nothing said to the Italian visitors) but the BOB in my breed, who went on to be placed in the Group for the first time for years, came from Italy so ...... how many new cases came from Cheltenham or Crufts is not known but I'd lay odds some of the increases seen, came from either, or both.

Cheltenham is in the UK, and they aren't facing the same set of restrictions that other places are. 

Not everything got cancelled.
