They are building something outside the law building. It could be many things, but as yet, the exact purpose of the structure is unclear. Top three guesses are:
A) An igloo, only made out of metal and not in Alaska...but whatever
B) Modern Art
C) The world's largest generator cozy
Also, this morning I'm sitting here reading in the law school cafe (yeah, we have a coffee shop...it's TVPNM after all), and this totally crazy guy runs up to me, asks me for a dime, and then goes "Let me give you a tip, sell all your stock in October...you can always buy it back for cheaper next year." Uh...OK Mr. Crazy Demented Drug Addled Mind Guy. Thanks for the tip.
