Yes, thank you, Mr. Chair. Now I'll have to be extremely polite, which is certainly unfortunate as I love to spar with my good partner, Mr. McKay.
I do have a couple of questions, Amy. I guess the big question I have is on the difference between what is happening with respect to the oil sands and the amount of money and infrastructure cost that occurs there versus in a conventional oil field. What analysis have you done that shows how much further investment it has taken to get the oil sands up and running--a project that has not been under construction for the last 30 or 40 years, but finally started--versus conventional oil fields?
