I also love the fact that people actually ride bikes there.
Here are some of the chained-up bikes I saw during my recent trip to NYC. I personally don't think I'd chain my bike up there; I'd find a safe indoor place to store it.
These guys have skills. I go to NYC probably 6 times a year for work, and I'm always amazed at the people riding bikes in traffic. Talk about defensive riding! I'd probably get squashed like a bug.
Oh, and please forgive the music - or turn down the volume.
