Thank you.
First of all, thank you for your questions. I'll try to answer the three parts quickly.
The resource estimate I referred to of 100 years is at the current production rate. It's really 100 years in North America. We in Canada are very much in the same position as the United States in beginning to develop these large shale plays. So the 100-year estimate is probably a conservative one at current production rates. We believe that here in Canada we can grow our production by approximately seven to eight billion cubic feet per day, incremental to where we're at today. When you look at the quantity of natural gas we propose here, if we were to capture 25% of the market share we would use less than one billion cubic feet.
So to answer your question, Canada has plenty of resources to run anywhere from 25% to 100% of our vehicles on natural gas.
