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 loves Sterile surroundings , bright artificial lighting and trying to find his way thru mazes .He did not want to see how to live on a Lunar Colony .None of the above choices .
