I’m an avid bicyclist—-road, gravel and mountain, and wouldn’t think of riding without a helmet. I’ve been in enough accidents where I’ve hit my head and was saved by the helmet. I only wear high-end helmets over $200. The cheap ones don’t offer the protection.
As for motorcycles, one vivid memory is of a stunning blond riding down the 5 in Orange County wearing only jeans and boots. Must’ve been 35 years ago. Truly a golden boy.
