SACRAMENTO, CA—Michael MacAlester, who ran away from his native Sacramento at 16 to join the circus, is not looking forward to the Big Top Circus' show this Friday in his hometown. "The idea of getting the hell out of Sacramento and joining a traveling circus was really exciting, but I guess I should've thought to check the schedule," MacAlester, 18, a unicycling clown, said Monday. "I asked the ringmaster if I could possibly sit this one out, but he said no way." MacAlester said he plans to wear extra-heavy make-up in case his parents happen to be in attendance.
