It’s definitely higher risk than a normal day running errands to the grocery store and grabbing a bite to eat but I’m not sure I’d call it unique. I was just watching a video from the Star Wars conference in Anaheim and there‘s thousands milling inside shoulder to shoulder for the entire day, Hockey and Basketball playoffs are packing in 20,000 like sardines screaming for hours, I worked a concert last night with 5,000 people singing and screaming for 3 hours, the casinos here are packed for Memorial Day, etc. Massive events are happening all across the country.
One thing I‘ve noticed while at the parks is we’re rarely in close proximity indoors to the same people for extended periods of time, which is when they say risk is the highest.
