I have a really strong feeling that a large percentage of the US doesn't really fully grasp the severity of COVID-19. Yes it's all over the news, and yes we're all discussing it now. But unless you live in a state, or part of a state, that has a heavy impact, it's really really hard to grasp the severity of it.
I live in Northern NJ, about 45 minutes out of Manhattan. My county has one of the highest amount of cases. The fear is real - I haven't seen my family that lives 10 minutes away in over a month. I have friends who are nurses in NYC and come home crying every day from work; they are surrounded by death every moment of their work day.
Because of what I've experienced, I do not feel that virus sniffing dogs & temperature checks prior to getting into a Disney park is an insane thing for them to implement. I don't think that ANY protective/preventative measure before entering a private property is insane. As a society, we need to change the way we interact with one another for a while - at least until we have a vaccine.
