Besides the fact that they were black or dark colors, ride black bikes, with black helmets and black shoes. Surely God would not object to a little blaze orange in the name of bike safety.

On another note, I was running to a suicidal person, not running code but booking it along nevertheless when I nearly tagged a guy running (no reflective attire AT ALL) on the roadway (4 lanes divided, 40 mph) when our beautiful hike/bike trail was four feet to the left. This is actually a crime (walking on roadway when sidewalk provided is the offense). I would have stopped if I hadn't been enroute to a call. Some people have no idea.
