No scientific benefit to wearing a mask if your sat outside socially distanced. I can understand for entry and exit to the stadium and getting up to go to the toilet. The only time you would need a mask once sat in your seat was if they let more fans in so distancing couldn’t be maintained.
This safety committee has gone above government advice on outside gatherings. What’s more frustrating is the likes of Leigh and Featherstone are selling tickets to away fans, Warrington are letting 4,000 fans in with standing terracing and Leeds are on TV now with hardly anyone wearing a mask.
