I think these are larger fanfests than they did before and some of them admitted on stage that they didn't expect it to be this hot, because they said they have usually done the NA fanfest at a different time of year.

But it shouldn't be like that so I hope they will do something such as allowing water bottles. Even without the heat outside, the amount of people breathing all the oxygen and producing their own body heat on a mass scale is going to overheat everybody on its own.
