I do wonder about status on a few of mine. On a recent bike I got on the craig, a similar bike "stolen" ad was up. Same size same salmon color frame but everything else different. I found myself checking back and forth comparing the pics for nicks in the paint, headset, etc. Nicks did not match up so I figured it could not possibly be it. So I went and bought it. I also have a rattle can flat black cdale that this thread brings to mind. One thinks why would somebody do that, 1st thing that came to mind is that it was a 'sleeper' anti theft measure. Didn't occur to me until later maybe it was not a pre theft measure but rather a post theft measure.. duh.
Last week I was riding through a neighborhood and somebody yelled out "they stole my bike" but I just keep riding when strange people yell things at me. I don't know if she was telling me somebody stole her bike or she thought I stole her bike. I think she was telling me why she wasn't riding.
