Some entries come up with no state listed. I believe the state should be New Mexico, but this should be verified before the data is modified.
I think this missing data is a result of a but in the data import script--there was an extra space in 'New Mexico' ('New Mexico') which prevented the script from finding a match. Please also check the data import script to make sure this error has been fixed.
