do you mean that little 4 wheeled go-cart the marines used a lot in viet nam? actually, they are fun to drive an all. The last time i saw one was in the movie "Maximum Overdrive"; it was the vehicle that had the M-60 machine gun mounted on it.
Now, if you are talking about that four to six legged (yes, i mean legs) device the army transportation group was working on to transport items over rough or uneven terrain, well they look fun too.
