I talked about natural gas opportunities in the north. The reality is that we're not going to put pipelines in place to get natural gas to many of those remote project opportunities; we're going to move it in two other ways: either as liquid natural gas or as compressed natural gas. You will move it in containers of one kind or another, for CNG or for LNG. You can move it by truck, you can move it by rail, you can move it by barge, or you can have intermodal transport for the movement of that product, either as LNG or as CNG.
Those are the alternatives to moving by pipeline. Pipeline is the most cost-effective.
