Heading into this convention on Opening the Space Frontier , I did not know what to expect . I hopped off the Metro in Crystal City in search of 12th Street and the Doubletree Hotel . I spent nearly 20 minutes navigating through the labyrinthine network of underground tunnels before I began to find my way . I thought that this is what living in an underground lunar colony must feel like : Sterile surroundings , bright artificial lighting and colorful art on the walls to make you forget where you are .

Question: Why is this preson going to the Opening of the Space frontier ?
Answer: The underground tunnels beckoned him .He wants to challange himself to find his way thru the labyrinthine network of underground tunnels .None of the above choices .He did not want to see how to live on a Lunar Colony .
