I've often thought that for the long-distance tourers among us, a permanent bike chain tattoo with the name of each state (or country) you toured through would be appropriate. My chain would be embarrassingly short, sadly enough.
As for the temporary tattoos, I'd enjoy having a book of them. Sometimes, you just need a bike chain necklace with the free end heading south. (Love that idea)
Give big space to the festive dog that make sport in the roadway. Avoid entanglement with your wheel spoke.
