One light ensor is ok for starters. It's not difficult to get an
additional light sensor. Most of us think the RIS should have come with
2 light sensors in the first place.

Have a look at some of the tracks here:

Thankfully, most competitions allow the use of two light sensors where
line following is involved. It goes to show that the organisers are real
people ;-)

Not at all. It's just that the line is most often defined as a dead
black strip 1 inch (or 2.5 cm) wide on a white background. Try
persuading the organiser to modify the line to suit your robot...
