Eventingsafety John (http://www.facebook.com/home.php?sk=lf#!/eventingsafety) brings up a really excellent point – these are the best in the world, why are they not wearing helmets?
Perhaps there should be a “Shame Cam” campaign, and if you are attending and watching warmups, etc., and see a rider without a helmet, take a picture and post it. Perhaps shame can keep them safer. ? How sad.
I hope American riders wear helmets…and are not caught on the Shame Cam.
