The Legend of Sleepy Hollow   We used sculptural trees on casters in our production, which made staging the famous ride fun for the actors as well as the audience.   Gregory Magyar, Edmonds Driftwood Players, Lynnwood, Wash.   Strobe light adds special effects to the Headless Horseman and blacklight and glu-paint add to the effects of the Lady in White and Major Andre.   Sheila Freudenberger, Orange Curtain Theatre, San Juan Capistrano, Calif.   We used black light and strobe with glo-paint for special effects. It worked well.   Sheila Freudenberger, Orange Curtain, San Juan Capistrano, Calif.
