I don't think that the designers of the art work in Denver  are an appropriate consultant
choice..  Denver Airport has the creepiest mural with an bizarre, occult theme....large Nazi in gas mask and dead children in of many cultures lined up in coffins.  It has been the subject of numerous documentaries.  I remember
the first time that I saw it.  Give me  the ""Eugene Flying People"" any day...light, whimsical and joyful.
