So where in the rest of the country does it tend to be used? Petrochemical plants, that's one thing.
Then with places like Pennsylvania and other areas that weren't that many years ago big natural gas producing areas and the U.S. producing more propane, is propane going to start to be shipped in from rail from the U.S. and not from western Canada into places like Sarnia? Are we going to see that begin to change the market going forward?
