Here we are hanging out at 900 N. Michigan Avenue in what we believe to be the coolest window on earth, for two reasons. One: it's a giant circle, and we can climb up the sides and slide back down on our bellies/bottoms/etc., all the while enjoying the view. And B, it's adjacent to our favorite toy store, a.k.a. Gant Toys, a.k.a. "The Truck Store." They also have airplanes, like the one Zak is holding.
