Warning: Warning sign ahead.
It is beleived the frenzy of warning signs has reached such a height that people will look back at 2006 as the "Warning Sign Epidemic".
One thinkingthinker was lucky enough to spot this particular useless warning sign on his way to a bad signage convention. He never did make it to the convention after a horrible death due to a blunt trauma inflicted by a warning sign stating 'Low Clearance'
It is a sad day for the thinkingthinkers sporting epitomised rational thought. A sad, sad day.
