I once saw a guy in a sombreo throwing handfuls of white stuff into the bike lanes under a train overpass bridge where the bike lane shared street level and the sidewalk was raised. He was swearing about hating cyclists and was odd but amusing.
Well on my way back ever cyclist had to dismount because the bike lane was covered in pigeons and slick with their fress droppings so you couldn’t pass or if you tried you would most likely slip due to the feces!
Moral of the story: do shit in a sombrero if you don’t want anyone to remember anything BUT the sombrero.
