One of the new shops is The Time Machine Shoppé with a demo portal directly connected to PanAm Games with 2-way traffic to increase the revenues of the Union Station Food Court. Look for the full-size DeLorean gimmick prop in the food court, and you'll see greeters leading you to enter the TARDIS booth where you can witness the Pan Am opening ceremonies (or any sporting event you wish to see of the full duration of the PanAm Games). Pedestrian traffic tranversing between 2015 and 2018 will be asked to sign a very strict legal waiver about avoiding temporal paradox situations.
