BROOKSVILLE — Perched on a stool at Crossroads Bar & Grill, Larry Obonnon stroked his handlebar mustache and looked over several fliers for a state campaign encouraging motorcyclists to wear brighter colors.

"I've been riding since the 1960s," said the gray-haired Obonnon, clutching a Budweiser, "and this stuff here ain't going to change a thing.''
