I wish I could tell you the experts in Transport Canada were further along on this and would have those numbers, but quite frankly they haven't done the work to find out, so they don't have any advice for us. If you look across the country to find out who's done work on it, it's pretty much the University of Manitoba.
Given this is such a critical issue in terms of transportation for our north, you would think we would have a lot more understanding of what's been going on, or what the possibility is, but the investment has not been made.
