I live in El Segundo and am an AMA member - I will volunteer to assit chartering a club with you even though I don't fly gliders there (though I might like to attempt it).

Redondo Beach just banned the flying of model aircraft from their boardwalks because of flyers hitting pedestrians and cyclists.

Had I been in the situation you were in at that time I would have encouraged the cyclist to call the police or ranger and get a police report and if possible hold him criminally liable for his actions.

Clearly the guy's an idiot - stupid kills but not nearly enough and not nearly enough of the stupid people.
