Dawes Eclipse 1.0

What happened

I went into my friend's apartment on a busy stretch of Ashland shortly after 7 pm and locked my bike on a street sign pole outside. When I return to my bike at 9:25, all I saw was my tire, still locked to the pole (with helmet locked in as well). I was in a hurry when I locked my bike, and must have accidentally locked just the wheel to the pole and not the frame without realizing it. The tire had been released and the frame taken. Another bike locked nearby seemed to have lost its wheel as well.
