The number is extremely large. I think there's general agreement on that from everybody who's gone through it. You're talking in the order of hundreds of billions of dollars of infrastructure deficit.
I'm not sure it's that important that we know exactly what it is. It's more important that we actually get on a plan that starts renewing, rebuilding, and putting investments into that infrastructure. We're continuing to build new infrastructure that will become old infrastructure before we deal with the old infrastructure that we have to continue to repair.
