When I was about 7, the company my dad work for supplied the concrete for what's now the
Aon Center tower; currently the 2nd tallest building in L.A.. It also has a huge foundation. Dad took me to see the job site during the pour. We were down in the pit at night and it was just surreal. Between the work lights and the walls of the pit, you couldn't see anything beyond the expanse of rebar. And it wasn't just the views out toward the edges of the pit that were disorienting, it was the view
down. We were walking on the rebar and you couldn't really see how far down it went. It was like being on another planet.
