A white is expected to attend the 11th Annual World Boating Expo here next week. 'I'll be looking at some of the speedboats,' the white said, 'but I don't think I can afford one this year.' The white, Jerry Strickler, 51, a Baltimore-area orthodontist, is slated to arrive at the boat show some time early Saturday and depart later in the day. It is believed he will wear slacks and a tie. 'I'm excited to have this white come to the show,' said Bob Elderbrecht, a boat show organizer. 'It will be easy to spot him, since he is a white.'
