Last night I sat at a red light in front of the Ames police station for about 2 minutes. For some reason I didn't trip the magnet--my bob trailer usually does. Anyway after no cars passed by and I didn't see any--Ames get's pretty quiet after 9pm--I just went. Seemed pretty irreverent to run a red light in front of the police station, but I figured the cops might wonder why I was loitering in front of the station??? I think you just have to use good judgement and hope that the police to as well. I have to admit I treat many stop signs as yield signs--but only at intesections were I have a clear view of traffic and will not interfere with anyone else.
