Will HHN 30 be canceled by COVID? It's too early to tell, but probably not. Information is changing daily, and we're seemingly on a downward trend than what was expected. I know there is a contingency plan in place in case we get to that point, as any smart business should have set for the rest of the year - but it is not expected. We're a little over 5 months out and a lot can change. Hell, things have changed from last week so...
Bottom line: I would anticipate HHN happening. Will there be impacts? Probably, yes. You'll probably see pulsing done. Less SIF (stuff in face). It's also possible you could see fewer actors in the streets.
This is an unprecedented time for all, especially the parks. They are taking it one day at a time, just like us. While it's scary to have so much up in the air, we shouldn't let the default response become the most severe.
