DEN - Denver International Airport. Give it a google and check out all the conspiracy theories. The art program is interesting, to say the least, but I have to say that I dig it. The terminal has aged tremendously well since its opening in the mid 90’s and the mountains provide a dynamic backdrop. The only downside is the hour bus ride into the city. Construction on the light rail connection is currently in the works so that will help alleviate the long commute.
