Let's have a dream!!! I want to suggest crazy idea about interesting show. This show is for excavators. You will need an "armwrestling" ground, two excavators and two stunt men. Stunt men will drive excavators and "fight" with a help of buckets. The winner will be one, who can turn over another excavator.
It is very expensive show, but very spectacular. The success of duel depends not on excavators, but on the mastery and ability of drivers.
