Dave Baum's Definitive Guide gives a good treatment for the case of a
single light sensor.
However, to follow a line as opposed to "edge following" with elegance
and ability to negotiate sharp 90-degree bends requires two light
sensors as was demonstrated on the next page:
http://www.geocities.com/laosoh/robots/linefollow2.htm
Two light sensors seems necessary and sufficient although Steve has ever
used three.
Btw, modifying the track, to me, amounts to cheating. A line is a line,
is a line ;-)
