"How do they expect goalies to do this?"
Rinks could probably make allowances for goalies only to use one locker room and just spend money and resources to clean that one room instead of using every single locker room for one team.
The deal is this: work with your rinks and follow the rules and stop coming up with ifs, ands or buts for why your team or your kid is special and can't follow the rules -- or doesn't have the discipline and responsibility to follow the rules -- and stop making excuses for why the rules are too hard to follow, or watch every rink slowly be sold to Amazon for warehouse space. It is what it is.
If kids can't wash their own uniforms, if they don't know how to stay 6 feet away, if they need a locker room to play hockey, maybe this isn't the sport for them anymore. This is not going to get solved by summer or by fall or even by next spring.
If rinks open and don't follow the rules, here is what will happen: people will start posting photos of your kids and parents not following rules, photos will go viral and news media will jump on it with headlines, and you'll have rink owners and hockey teams fielding calls and complaints forever.
And god forbid there's a Patient Zero at some rink that causes an entire regions to shut down again -- or a death -- and that's the end of youth hockey this year, next year and possibly for good. The end.
Read the rules. Come up with solutions. Do more than you have to. Some teams will and they will be the ones still playing next season. This season is gone.
