This is not the most captivating story, but one time about four years ago I was cycling the Santa Ana River trail around late afternoon, almost dusk, and came upon part of the Element team trying to film at a spot (no one really got anything, unless it was before I arrived).
This wasn't the wide open "Skip's Ditch" portion of the river either, this was under the Garden Grove Boulevard bridge; it's narrower, the trail curves, and there's lower visibility. This is the highest traffic time of day, bicycle-wise, and the shadows are long and dark. While everyone else is minding themselves pretty well, Madars Apse decides that all he wants to do is skate flatground directly under the bridge where he's shrouded in total darkness until the last second from all incoming cyclists taking the roll in down directly at him, and he can't really see them until they're hurtling at him.
There were no true close calls, but it was pretty shitty. I saw had old ladies panicking and swerving (but recovering), you had serious cyclists riding with good speed having to veer into the oncoming lane...and he never made an attempt to move. There were no true close calls due to luck, but basically every cyclist he encountered was panicking –– it was entitled and gross. He stayed there for a long time too. I yelled over to him to knock it off from where I stopped to watch for a minute, but he just ignored me. I wasn't really in the mood, so I kept on riding, but it was definitely a display of bad character.
