Benjammin,
If my geography is correct doesn't Martin Stadium have a set of bleachers that faces the west? If you were sitting on that side I would say the temp easily exceeded 100+ for the game since the hottest part of the day is usually between 2 pm and 6 pm.
This does give me an idea for those outdoor concerts at the Idaho Center in Nampa I have attended and the so-called officials will not allow anyone to bring water of your own within the outdoor arena, but the concession jerks want $5.00 per 16 oz bottle of water. For the price of one bottle of water you could get the ice and the concession kid, the one who sells the ice to you, would get a $2.00 tip.
