DO IT YOURSELF ENTRY --- PURPOSE: To indicate to blind students and staff in a school hallway that they are moving to the left side of the hall into oncoming students. Apply a colored "tap strip" down the middle of the hall for its entire length. The strip is easily seen by sighted staff, and it returns a distinct sound and feel when tapped by the blind students' canes. TITLE: Hold That Line (in Springboard). AUTHOR: Pfotenhauer, M..
