No they didn't, did they. I took a photo of one guy sitting next to his bike with the number clearly visible and sent it to National Park officer who deals with these issues. He said not worth pursuing as there was no evidence the guy had actually ridden his bike! Pushed it halfway up to the col, I s'pose. It is noticeable, though, what tiny number plates a lot of these bikes have, as if they didn't want to be identified! Isn't there a minimum legal size for the letters/numbers?
