I think it’s entirely sensible to make a point out of someone unusual for us Brits.
After all we are very stupid a lot of the time. There’s plenty of evidence.
I’ve ridden before 10am in 40 degrees in Vegas and the guy who took us said plenty of people die out here.
So yeah worth a heads up.
You can work with the weather, go early, drink, stay in shaded areas where possible but it’s good to know it’s coming.
