I saw two of these trucks in Car & Driver.  Very nice.  One was from
Nebraska (more looks) and one from a school that Started with a "C" I
think.....  (name of school was on the truck, it was also helped by
Lieningfelter (sp?) Engineering)

All in all very nice work from both schools.  I would have liked to have
seen all the trucks that were in the contest.
