This is old, but it's still viable entertainment. Crazy dude gets pissed at the town mayor and thinks long and hard about the best way to take out his anger issues. Egg the Mayor's house? TP the trees? Blow up an mailbox? Salt his lawn? Kick his dog? Nah, guy builds himself a Road Warrior/Gauntlet worthy death vehicle. It's your basic bulldozer jobby with a pair of 50 cals, closed circuit TV monitors, and concrete reinforced armor. No biggie. Only took a few weeks to build in a secret base outside of town.
The most interesting detail of the entire rampage, is the fact that once the dude fitted the armor top on (using a crane while inside the beast), there was nooooo way for him to take it back off again. He was in it to win it. That's the kinda determination that once made this great country proud. But he wasn't determined enough to see it through to the end. He went out in the fashion that currently makes this great country proud.
Want to jump start the economy? Set up some guidelines, draw up the legal deathrace papers, have 'em sign, and let these crazy bastards loose in an arena and charge 50 bucks an episode. MY MONEY IS READY.
