I don't think there's a target rate. Depending on the method of tolls and tariffs, I think the market understands a pipeline cannot be always full if the demand side is variable, subject to storage. I don't think there's a fixed number. It's obvious that everybody benefits from a pipeline moving all the capacity it can, because the cost per unit of gas or oil is reduced the more you utilize it. So I'd say 100% is desirable. It's actually happening on some oil pipelines right now, including Kinder Morgan, I believe. Gas pipelines are a different story, where you've got quite a bit of space that could be occupied if there were either more supply or more demand for the gas.
