They asked McKenzie about this on his show. He didn’t seem to know about that rule and he said they used both the cooling benches (Which on the broadcast they said the bills shipped there themselves) and the mister fans. He said the benches worked ok for him because he is small but Dawson Knox was sitting next to him and said he could barely feel anything. He said they used the mister fans initially but then turned off the mist part because it was making the inside of their helmets wet. Oh and they were blowing out hot air so they were useless.
