Chris Moneymaker announced he won't be at this year's WSOP. He doesn't want to risk bringing covid home to his family. I think we can expect to see a lot of famous names not show up.
In my travels I've noticed that casino business is way down where they reinstated wearing masks. People don't like wearing them and neither do I. It's hard to breath with the damn thing on. Having to wear a mask for 12 hours a day at the WSOP is not something I would want to do.
