We participated with the Government of Alberta back in 2005, I think it was, in doing their first group of studies, when we contributed $100,000 towards that effort. At that time, the numbers that came out of that study were a little bit different from what we understand the current numbers to be.
The studies looked at a couple of options in terms of the potential system they could use there. I'm assuming that the numbers you're referring to are probably what I'll call equivalent to a higher-speed system using the current corridor.
