Yes but there are still rules about not travelling further than necessary while we're still in partial lockdown, albeit with some loosening of restrictions. What we all want, I'm sure, is a full stadium in August and the only way we're likely to get that is by avoiding a third wave before then.
The test is around the protocols of getting some people into and out of stadiums safely, plus the requirement to be tested and/or vaccinated, not the travelling itself. But why increase the risk, when we seem to be getting on top of this finally?
