When we were they the end of May the performers were very sweaty. When they brought kids out to dance with them, they were spraying them with their sweat. I cant imagine how bad it will be in july//august.
Living in South Florida, the humidity is ridiculous. I break a sweat going to get the mail in t-shirts and shorts. But to do anything in a full suit just must be absolutely brutal. I don't envy them.
When it was running at DCA it was quite common for performers to pass out/throw-up/collapse/whatever else right after they hit step down.... and there's no humidity there
