Colorado is having a wave right now, so there are going to be a lot of cases everywhere. I bet a lot of these people already had covid before the hockey game. You're not going to be able to avoid exposure forever, so if you want to be safe, get the vaccine, and get the booster shot, which restores efficacy back to 90+% against symptomatic infection. That's what I did. I can't stand how experts are still declaring certain activities "unsafe". It's nearly 2 years in, and unreasonable to expect people to still put their lives on hold, when we have vaccines and treatments readily available.
