a week or two ago, this girl who locks her bike up outside of my apartment alot locked just her front quick release to a pole. I seriously thought about taking the frame and rear wheel into my building and leaving a note. In the end i decided that it would be too much trouble for her to get it back and just left a note that basically said that she was a complete idiot who didn't want her bike anymore if she ever left it like that again (of course i used nicer language) and i dropped the link to sheldon brown's locking page.
