We have played n games in Northern CA when it is 110. Brutal conditions, but at least it wasn't turf. My oldest daughter literally fainted due to heat in a game a few years ago, scared the hell out of us. It turned out she had been eating a ton of seeds and not drinking anywhere near enough water. But they had her in for EKG's after the same thing happened at school a few days later.
We played in your Elk Grove earlier this year it was 104. Once in Folsom it was 105, DD didn't pass out, but was very close and had to sit out the next day games.
