We asked our boyfriends six-year old son about monster trucks and he firmly said, They are always red or blue and they look like Hot Wheels and they are really fast and loud! Well test that theory at the Monster Jam event featuring big-boy toys Grave Digger, Iron Outlaw, El Toro Loco, Monster Mutt, Bounty Hunter, Donkey Kong, Batman, Captains Curse, Arachnophobia, Martial Law, Terminator, and McGruff. While the sport of monster-truck racing seems lowbrow, the science behind it is nothing short of mechanical genius. Think about it: folks transform lowly pickups into 10,000-pound car crushers, capable of speeds up to 80-miles per hour. Now thats some intelligent design.
