A bulldozer driven for entertainment is an affront to nature in its implication, and likely consequences. A bulldozer driven to alleviate mental and emotional stress, is a loose cannon. A bulldozer fuelled and ready to lurch into action is a disaster waiting to happen. In all of this, is the idiom of nation, the pedalling of a frontier battered into submission. It is the wren\'s nest tumbled under the blade, the echidna dismembered, its quills signing off on the travesty of \'development\'. If you listen, even from a fair distance, you will hear the rumbling of the CAT engine, carried on the wind-above it, sits a composer of destruction, smug with work ethic but thoroughly enjoying his mission.
