Tag the Line is by Will Orlich, Bradenton, Fla.; Tag the Line Half is by John Steckman, Ellwood City, Pa.; Tag the Line 3/4 is by Bob Dawson, Sarasota, Fla. I don't know who's associated with Tag the Line One Quarter. All "Tags" go back to Tag The Centers by Holman Hudspeth, Detroit, Mich.
From lines, waves or two-faced lines (including three and one lines): All face down the line. Tag the Line One Quarter--leads step forward until shoulder to shoulder in the center. Half Tag The Line--All walk forward, leads pass by one couple and stop when shoulder to shoulder with trailers from the other side (in a wave without joining hands unless so directed). Tag The Line Three Quarters--All walk forward, leads pass thru two couples and trailers stop when shoulder to shoulder in the center with the trailers from the other side (in a wave without joining hands unless so directed).
