LAS VEGAS (AP) — On the Fremont Street pedestrian mall, Michael Troy Moore can be found wearing nothing but a G-string and a stuffed rooster on his lap while he plays heavy metal music.To him, that's good-natured comedy.Inside the confines of Las Vegas City Hall on Tuesday, though, Moore dressed far more conservatively to air his grievances with a proposed ordinance aimed at creating order in the chaotic confines of the downtown Las Vegas mall that officials say are driving tourists and families away."Talent is not the threshold for us to be there," he told the city's attorney.
