Thank you. Those, I think, are two important points.
I don't know if Mr. Mansfield and Mr. Janzen have something to add. Would you agree that those have been two sorts of roadblocks in the past?
I appreciate what you've indicated, Mr. Wark. Are there any other roadblocks or is there anything else you think we should be identifying so that we can try to find a way to move forward? Does anybody want to respond to that?
