I guess this qualifies for a traffic stop.....
I'm an obvious night owl, and I have mentioned this on SF before, but I work out late at night or early in the morning depending upon how you want to look at it. But earlier in the summer I decided I wanted to take a run thru the downtown city area where I live. I was running thru the down town area, on the berm of the road, not the side walk. It was about 2am. Being in my own mind and deep in thought I suddenly noticed the red and blue lights behind me. I could hear vehicle noise so I just thought well the police has got someone. I didn't do anything and just kept running. I them heard the officer burp the siren twice and I thought WOW, this is serious. So I ran upon to the sidewalk, stopped and turned to see what was going on.
It was me they were pulling over. The officer wanted to know what I was doing and where I was going. I told him I was just out for a run. The officer flashing the light in my eyes said, I'm more interested in what you're running from at 2 AM! I pleaded my case and he let me go, I cut my run short and went home. I'm not sure he believed me, because I was only home about 15 minutes when he called to check on me. I don't run after dark anymore. Lesson learned.
