Exactly...life's too short for even just one worker/driver/team member/ fan etc .to fall to heat exhaustion or anything else serious. Everyone handles weather conditions differently, if you are a hero and can do it all outside in this extreme heat wave, my hat's off to you.
Let's just respect the decision they have made....and either go to another track or enjoy a night of family time.

If the heat isn't an issue, then build a bonfire and roast some marshmallows !
