  I just surveyed a bunch of roads in rural Illinois, and the Tiger data is 
all off by 20-30 meters.   The Tiger data seems to have been defined using 
math from the original survey, and does not even include the doglegs where 
adjoining townships meet.    This error is related to the distance from the 
original chain survey from the baseline and meridian lines in Illinois.   A 
famous set of survey doglegs is North Avenue (Rt 64) near Chicago -

  The north and south streets don't match.

  All this from the region where the surveyors produced "Lake Wobegone" <g>
