[meteorite-list] Colorado Meteorite Locations on Google Earth

If any coordinates published in the MB are in error, please submit
the correction to the Editor, Harold Connolly
<meteorite_at_kingsborough.edu> or one of the AEs. If you can support
the correction, it will be made in the database right away and an
erratum will be printed. None of the MB coordinates are ever
rounded, at least not intentionally. Also, using the wrong datum as
stated will not cause errors of more than a few 10's of meters.
