Truth be told...
I do, actually, always proper gear when riding.... I'm no newbie to bikes... I am well aware of potential consequences. Although I have ridden in shorts, I don't like the sensation of (silly as it sounds) the air rustling my leg hair... it's annoying to me.

Here in Pennsylvania, it is legal to ride helmetless... However, I do wear a helmet, because I choose to... just as I choose to wear a kilt, when I feel like it, and accessorize it any darn way I please.

If these guys want to wear a kilt while riding, one day out of the year... Good for them! I'd much rather see that, then the daily selfish buttcheeses who feel it's necessary to yak on the cell phone while zipping down the road, 24/7.
