Mr. Weiler, it just comes down to the cost impact and whether or not you're looking at using and utilizing existing infrastructure that we currently have that can move clean molecules versus building new additional infrastructure. That's the difference.
I think Mr. Patzer brought up the impact assessment in terms of building the new pipes. That's what makes our existing system so valuable and important right now; it's to utilize that infrastructure. Whether it's the existing pipes or the right-of-ways, it's really making sure that we're not ignoring the extreme value, the huge value, that our existing infrastructure has and the value that investors put in the ground and our customers have paid for. To build something new without figuring out how much you can use of the existing infrastructure would be a little bit short-sighted, I think.
Now, whether or not we look 50 years out and we see something that might change in year 10, 20, 30 or 40, then yes, we can shift, but we don't know enough now to shift away and say that we shouldn't be investing and continuing to make sure that these systems are resilient.
If I had more time, I'd tell you all about Texas. It's a great lesson learned about how not to do it.
