I'm being completely prejudice and have no proof that this guy was transporting a stolen bike, but it damn sure looked like he was in possession of a road bike that didn't belong to him.
As I'm driving on Balboa, I see a heavy built Mexican guy in his late 30's or early 40's riding a bicycling while holding the stem of a road bike alongside him. I pulled out my cell phone camera and took a video and a still photo, but the quality sucks way too much to be worth anything. I got the guy's face, but barely. I didn't really give a hoot that he saw me videotaping him.
I got home and reviewed the footage and it's all pretty useless. My phone's video quality of horrible. No purpose in posting anything and I didn't even get a good look at the bike's brand name.
It wasn't until today that I realized how hard it is to follow someone on a bicycle when you're driving a car. It's not that I minded being completely obvious to him that I was watching and following him. It's that the other cars on the road would give me crap for driving 7mph on a one lane public road in a big City.
This was the one time I wish I had a bike with me rather than my car - all so I could follow the guy to see where he goes. He turned from Balboa to Fulton at about 10th Avenue or so, but that's the last I saw of him.
