Activists like to get attention, but Sardar Biglari is aiming higher than most. Literally. The founder of the San Antonio, Tex.-based Lion Fund, Biglari has bought billboard space in Massachusetts to convince shareholders of Springfield, Mass.-based Friendly Ice Cream Company to elect he and a colleague to Friendlys board of directors. Vote for Biglari and Cooley, the billboards read. Good for Employees, Franchisees and Shareholders.
