The Graffiti Story Cupboard

Where I live you don't see much in the way of graffiti.  Oh, there's the usual spray painted road signs which turn 30mph into 80mph but we've learned to ignore such things.  After all, if you're going around a twisty curve you know you're not going to make it going 80 and if a deer jumps out in front of you?  Well, it's not pretty.

As for the graffiti I saw which prompted this post, it was written on the red plastic side of a cart holder (not sure what they call those things where you put your grocery cart when you're finished with it so cart holder will have to do :).  I noticed it because I'd never seen writing on this particular holder at the grocery store where I shop.  And second, it was a very cryptic message.  Neatly printed in black magic marker was "Beware the Rinker Biker Bitch".  If you're like me, all sorts of stories began to dance around in my head.

Who had written it and why?  Who was the Rinker Biker Bitch and what did she do to this person?  Where I live the closest thing to a biker chick that I've seen is a retired woman and her husband out for a ride on their very expensive Harley.  Definitely not this Rinker person.  So where did she come from?  How does she hide her secret identity from people who know the Biker Bitch?  Is she an undercover cop or just a wild woman out for a bit of bitchy fun?

So, what kind of interesting graffiti has popped into your life and did it inspire a story?
