Actually we used one of the 3x7 melamine boards from Home Depot. These are
easier to transport in a car, they have a pretty good surface for line tracking,
and they are quite inexpensive. Using only one, however, was very crowded for
the mobile robots. But we managed to squeeze them in ... including a wonderful
"first" for us: the dump truck did a three point turn using line tracking.

That's right! When the dump truck arrives, the lifting mechanism stops, the
hopper doors open, dumping the balls, and then the doors close again. Finally
the lifting mechanism starts again. The reason it stops is to prevent balls from
jamming the hopper doors when they are closing. You *know* it's going to happen
more often than not!
