  Quotations
  Infrastructure: It's our roads, bridges, dams, levees, airports, power grids... basically, anything that can be destroyed in an action movie... The problem is, though, when our infrastructure is not being destroyed by robots and/or saved by Bruce Willis we tend to find it a bit boring.
