I worked at a country club for 10 years and it gets HOT here. lol Everyone played early in the morning and late in the afternoon. Only a few brave souls were on the course during the day.
Those folks were brave it they were young. If they were old timers then they were STUPID FOOLISH. It is dangerous to be out in that heat: hyperthermia, heat exhaustion, heatstroke, heat cramps, sunburn, heat rash.
I'm sure that your club had to occasionally take care of overzealous golfers during the summers.
