..I might be on to something.  it seems PostGIS is kicking out slight 
asText() variations my PHP parser isn't expecting.  for instance, there are 
a very few points that have stray parens either before or after them.  note 
the XML for an offending polygon, below.  I stumbled onto the solution by 
throwing some of my encode strings at this 
site<http://facstaff.unca.edu/mcmcclur/GoogleMaps/EncodePolyline/decode.html>, 
which showed an occasional "0" for a lat or long.  I think, if i try to 
strip ( or ) out of the text before pushing the lat/long points into the 
array, everything will come to life:
