I was able to run the script several days ago without problems and don't remember making any significant modifications since that time.  In the meantime, I have received an update to OGR.  Could this be a bug introduced by the update?

Spencer,

It is indicating that for some reason landGeom is None, the null value
for python.  I don't see anything odd about the script so perhaps there
are actually features in this dataset that are null.
